Introduction to web APIs - Learn web development
they are based on objects your code interacts with apis using one or more javascript objects, which serve as containers for the data the api uses (contained in object properties), and the functionality the api makes available (contained in object methods).
...the most obvious ones are: audiocontext, which represents an audio graph that can be used to manipulate audio playing inside the browser, and has a number of methods and properties available to manipulate that audio.
...ng, stop it } else if (this.getattribute('class') === 'playing') { audioelement.pause(); this.setattribute('class', 'paused'); this.textcontent = 'play'; } }); // if track ends audioelement.addeventlistener('ended', function() { playbtn.setattribute('class', 'paused'); playbtn.textcontent = 'play'; }); note: some of you may notice that the play() and pause() methods being used to play and pause the track are not part of the web audio api; they are part of the htmlmediaelement api, which is different but closely-related.
...its context object is created by getting a reference to the <canvas> element you want to draw on, and then calling its htmlcanvaselement.getcontext() method: const canvas = document.queryselector('canvas'); const ctx = canvas.getcontext('2d'); anything that we want to do to the canvas is then achieved by calling properties and methods of the context object (which is an instance of canvasrenderingcontext2d), for example: ball.prototype.draw = function() { ctx.beginpath(); ctx.fillstyle = this.color; ctx.arc(this.x, this.y, this.size, 0, 2 * math.pi); ctx.fill(); }; note: you can see this code in action in our bouncing balls demo (see it running live also).

mozbrowsershowmodalprompt
the mozbrowsershowmodalprompt event is fired when the content of a browser <iframe> calls the window.alert(), window.confirm(), or window.prompt() methods.
... message a domstring representing the value passed to the window.alert(), window.confirm(), or window.prompt() methods within the browser <iframe>'s content.
... returnvalue a domstring representing the return value for the window.prompt() methods.
... initialvalue a string representing the initial value for the window.prompt() methods.

HTML parser threading
the nsistreamlistener methods (onstartrequest, ondataavailable and onstoprequest) are called on the main thread.
...passing data to the parser thread nshtml5streamparser gets some of its methods called on the main thread and some called on the parser thread.
...these two methods along with timerflush (discussed later) are the entry points from the parser thread event loop into nshtml5streamparser.
...nshtml5atom objects are guaranteed to be immutable and to stay alive for the lifetime of the parser instance, so it's safe for the main thread to call their methods (as is necessary to find the corresponding normal atom).

AddonManager
the majority of the methods are asynchronous meaning that results are delivered through callbacks passed to the method.
...to do so many methods of the addonmanager take the add-on types as parameters.
... startup change types these constants represent the lists of types of changes that can occur to add-ons during startup; they're used with the getstartupchanges(), addstartupchange(), and removestartupchange() methods.
... methods addstartupchange() adds an add-on change from the add-on changes list.

Memory reporting
methods ...
... size_t mystring::sizeofexcludingthis(mozilla::mallocsizeof amallocsizeof) const { return amallocsizeof(mbuffer); } size_t mystring::sizeofincludingthis(mozilla::mallocsizeof amallocsizeof) const { return amallocsizeof(this) + sizeofexcludingthis(amallocsizeof); } (note that sizeofexcludingthis and sizeofincludingthis aren't overrides of methods on a global base class that is common to all reporters.
...that said, note that for some classes these methods may be virtual.) mfbt/memoryreporting.h defines mozilla::mallocsizeof as follows: typedef size_t (*mallocsizeof)(const void* p); functions with this signature measure the size of p by asking the heap allocator how big it is (via moz_malloc_usable_size).
... the override annotations say that d's methods override the corresponding methods in b.

NSPR Poll Method
each i/o layer is represented by a prfiledesc structure and the protocol of that layer is implemented by a priomethods table.
...the poll method is one of the functions in the priomethods table.
... new_flags = fd->methods->poll(fd, pr_poll_read, &out_flags); if you are going to call pr_send, pass pr_poll_write as the in_flags argument.
... new_flags = fd->methods->poll(fd, pr_poll_write, &out_flags); if you are interested in calling both pr_recv and pr_send on the same file descriptor, make two separate calls to the poll method, one with pr_poll_read as in_flags and the other with pr_poll_write as in_flags, so that you know what events at the network transport layer pr_poll_read and pr_poll_write are mapped to, respectively.

JS::Value
the different representations are visible using the separate int32/double methods but do not affect observable semantics (ignoring performance).
...(note that both -0 and +0 are allowed, and the latter may sometimes be stored using the int32_t representation.) js::value further provides these methods combining various aspects of the above methods: js::objectornullvalue(jsobject*) returns an object value corresponding to the given non-null pointer, or a null value if the pointer is null.
...the now-deprecated jsval methods allowed jsval_to_object(val) when jsval_is_null(val), but this was a source of constant bugs.
...the old jsval_is_* methods, jsval_* constants and *_to_jsval methods, and jsval_to_* methods are also deprecated; uses of each should be replaced with use of the corresponding val.is*(), *value(), and val.to*() methods.

JSFastNative
apis such as js_initclass and js_definefunctions can create custom methods that are implemented as c/c++ functions of this type, instead of jsnative.
... native methods must not call js_callee after calling js_set_rval.
... native methods must not call js_this after calling js_set_rval.
... native methods must not call js_this_object after calling js_set_rval.

Using the Places annotation service
most methods in the service are duplicated with one method labeled as a 'page annotation' taking an nsiuri and the others labeled as an 'item annotation' and taking the id of an item in the places database.
... the getter functions return only the value of the annotation (with the exception of the c++ getpageannotationbinary and getitemannotationbinary methods which return the mimetype as well).
...to add or remove an observer use the methods: addobserver(aobserver); removeobserver(aobserver); where aobserver is an object implementing the nsiannotationobserver interface.
... the objects must implement four methods, which are called when an annotation is set/removed on a uri or item respectively: onpageannotationset(auri, aname); onitemannotationset(aitemid, aname); onpageannotationremoved(auri, aname); onitemannotationremoved(aitemid, aname); var observer = { onpageannotationset : function(auri, aname) { }, onitemannotationset : function(aitemid, aname) { }, onpageannotationremoved : function(auri, aname) { }, onitemannotationremoved: function(aitemid, aname) { } } annotationservice.addobserver(observer); } ...

Bundling multiple binary components

Packaging WebLock
the installation script for the weblock component can also be used to register the component with the browser into which it is installed (see registration methods in xpcom for more information on registration).
... javascript apis from the xpinstall install object download the jar in which the installable files appear and call registration methods that tell mozilla about the new component and the ui it uses to access the weblock component.

XPCOM Stream Guide
if you have an input stream called nativestream, you can use code like this: var stream = components.classes["@mozilla.org/scriptableinputstream;1"] .createinstance(components.interfaces.nsiscriptableinputstream); stream.init(nativestream); the stream provides .read(count), .available(), and .close() methods.
... fileutils.jsm provides apis for getting output streams for files, with the .openfileoutputstream(file, modeflags) and .opensafefileoutputstream(file, modeflags) methods, and for closing those output streams with the .closesafefileoutputstream(inputstream) method.
...(this is particularly true of streams that reach out over a network connection, like http and ftp channels.) stream listeners implement three methods.

... unlike the similar methods in the fetch api, which only allow the method to be invoked once, these methods can be called multiple times.
... messages received through the push api are sent encrypted by push services and then automatically decrypted by browsers before they are made accessible through the methods of the pushmessagedata interface.
... methods pushmessagedata.arraybuffer() extracts the data as an arraybuffer object.

Selection - Web APIs
methods selection.addrange() a range object that will be added to the selection.
... behavior of selection api in terms of editing host focus changes the selection api has a common behavior (i.e., shared between browsers) that governs how focus behavior changes for editing hosts after certain methods are called.
... note: the selection api methods may only move focus to an editing host, not to other focusable elements (e.g., <a>).
... the above behavior applies to selections made using the following methods: selection.collapse() selection.collapsetostart() selection.collapsetoend() selection.extend() selection.selectallchildren() selection.addrange() selection.setbaseandextent() and when the range is modified using the following methods: range.setstart() range.setend() range.setstartbefore() range.setstartafter() range.setendbefore() range.setendafter() range.collapse() range.selectnode() range.selectnodecontents() glossary other key terms used in this section.

Advanced techniques: Creating and sequencing audio - Web APIs
let's create a simple one so we get used to the methods we need to create an envelope with the web audio api.
... this is really useful — now we can start to harness the power of the audio param methods on the gain value.
... we can set a value at a certain time, or we can change it over time with methods such as audioparam.linearramptovalueattime.
...fer = buffer; let bandpass = audioctx.createbiquadfilter(); bandpass.type = 'bandpass'; bandpass.frequency.value = bandhz; // connect our graph noise.connect(bandpass).connect(audioctx.destination); noise.start(); } "dial up" — loading a sound sample it's straightforward enough to emulate phone dial (dtmf) sounds, by playing a couple of oscillators together using the methods we've already looked at, however, in this section, we'll load in a sample file instead so we can take a look at what's involved.

Migrating from webkitAudioContext - Web APIs
changes to the creator methods three of the creator methods on webkitaudiocontext have been renamed in audiocontext.
... if your code uses either of these names, like in the example below : // old method names var gain = context.creategainnode(); var delay = context.createdelaynode(); var js = context.createjavascriptnode(1024); you can simply rename the methods to look like this: // new method names var gain = context.creategain(); var delay = context.createdelay(); var js = context.createscriptprocessor(1024); the semantics of these methods remain the same in the renamed versions.
... changes to starting and stopping nodes in webkitaudiocontext, there are two ways to start and stop audiobuffersourcenode and oscillatornode: the noteon() and noteoff() methods, and the start() and stop() methods.
... (audiobuffersourcenode has yet another way of starting output: the notegrainon() method.) the noteon()/notegrainon()/noteoff() methods were the original way to start/stop output in these nodes, and in the newer versions of the specification, the noteon() and notegrainon() methods were consolidated into a single start() method, and the noteoff() method was renamed to the stop() method.

Window - Web APIs
that said, even in a tabbed browser, some properties and methods still apply to the overall window that contains the tab, such as resizeto() and innerheight.
... methods this interface inherits methods from the eventtarget interface and implements methods from windoworworkerglobalscope and eventtarget.
... methods implemented from elsewhere eventtarget.addeventlistener() register an event handler to a specific event type on the window.
... deprecated methods window.back() moves back one in the window history.

Box alignment in Multi-column Layout - CSS: Cascading Style Sheets
the box alignment specification details how alignment works in various layout methods; on this page we explore how box alignment works in the context of multi-column layout.
... as this page aims to detail things which are specific to multi-column layout and box alignment, it should be read in conjunction with the main box alignment page which details the common features of box alignment across layout methods.
... column-gap the column-gap property was specified in earlier versions of the multiple-column layout specification, and has now been unified with the gap properties for other layout methods in box alignment.
... while other layout methods treat the initial value of column-gap as 0 multicol treats it as 1em, as in general you would not want to have no gap between columns.

Allow - HTTP
the allow header lists the set of methods supported by a resource.
... this header must be sent if the server responds with a 405 method not allowed status code to indicate which request methods can be used.
... an empty allow header indicates that the resource allows no request methods, which might occur temporarily for a given resource, for example.
... header type entity header forbidden header name no syntax allow: <http-methods> directives <http-methods> the comma-separated list of allowed http request methods.

If-Match - HTTP
for get and head methods, the server will send back the requested resource only if it matches one of the listed etags.
... for put and other non-safe methods, it will only upload the resource in this case.
... there are two common use cases: for get and head methods, used in combination with a range header, it can guarantee that the new ranges requested comes from the same resource than the previous one.
... for other methods, and in particular for put, if-match can be used to prevent the lost update problem.

Details of the object model - JavaScript
a class defines all of the properties that characterize a certain set of objects (considering methods and fields in java, or members in c++, to be properties).
...in that definition you can specify special methods, called constructors, to create instances of the class.
... definition define a class with a class definition; instantiate a class with constructor methods.
... another way of inheriting is by using the call() / apply() methods.

Functions - JavaScript
read more about objects and methods in working with objects.
... it turns out that functions are themselves objects—and in turn, these objects have methods.
...an object containing methods for manipulating the inner variables of the outer function can be returned.
...however, it does not possess all of the array-manipulation methods.

Grammar and types - JavaScript
for example: '37' - 7 // 30 '37' + 7 // "377" converting strings to numbers in the case that a value representing a number is in memory as a string, there are methods for conversion.
... enhanced object literals in es2015, object literals are extended to support setting the prototype at construction, shorthand for foo: foo assignments, defining methods, making super calls, and computing property names with expressions.
... var obj = { // __proto__ __proto__: theprotoobj, // shorthand for ‘handler: handler’ handler, // methods tostring() { // super calls return 'd ' + super.tostring(); }, // computed (dynamic) property names [ 'prop_' + (() => 42)() ]: 42 }; regexp literals a regex literal (which is defined in detail later) is a pattern enclosed between slashes.
... the following are examples of string literals: 'foo' "bar" '1234' 'one line \n another line' "john's cat" you can call any of the string object's methods on a string literal value.

Text formatting - JavaScript
const foo = new string('foo'); // creates a string object console.log(foo); // displays: [string: 'foo'] typeof foo; // returns 'object' you can call any of the methods of the string object on a string literal value—javascript automatically converts the string literal to a temporary string object, calls the method, then discards the temporary string object.
... a string object has a variety of methods: for example those that return a variation on the string itself, such as substring and touppercase.
... the following table summarizes the methods of string objects.
... methods of string method description charat, charcodeat, codepointat return the character or character code at the specified position in string.

Inheritance and the prototype chain - JavaScript
inheriting "methods" javascript does not have "methods" in the form that class-based languages define them.
...// o ---> object.prototype ---> null var b = ['yo', 'whadup', '?']; // arrays inherit from array.prototype // (which has methods indexof, foreach, etc.) // the prototype chain looks like: // b ---> array.prototype ---> object.prototype ---> null function f() { return 2; } // functions inherit from function.prototype // (which has methods call, bind, etc.) // f ---> function.prototype ---> object.prototype ---> null with a constructor a "constructor" in javascript is "just" a function that happens to be called with t...
... summary of methods for extending the prototype chain here are all 4 ways and their pros/cons.
...additionally, the initialization of the constructor may put unwanted methods onto the object.

Deprecated and obsolete features - JavaScript
regexp methods the compile() method is deprecated.
... object methods watch and unwatch are deprecated.
... date methods getyear and setyear are affected by the year-2000-problem and have been subsumed by getfullyear and setfullyear.
... string methods html wrapper methods like string.prototype.fontsize and string.prototype.big.

Warning: String.x is deprecated; use String.prototype.x instead - JavaScript
the non-standard generic string methods are deprecated and have been removed in firefox 68 and later.
... string generics provide string instance methods on the string object allowing string methods to be applied to any object.

Arrow function expressions - JavaScript
arrow function expressions are ill suited as methods, and they cannot be used as constructors.
... https://www.ecma-international.org/ecma-262/10.0/index.html#sec-strict-mode-code https://www.ecma-international.org/ecma-262/10.0/index.html#sec-arrow-function-definitions-runtime-semantics-evaluation correction: end invoked through call or apply since arrow functions do not have their own this, the methods call() and apply() can only pass in parameters.
... function foo(n) { var f = (...args) => args[0] + n; return f(10); } foo(1); // 11 arrow functions used as methods as stated previously, arrow function expressions are best suited for non-method functions.
... let's see what happens when we try to use them as methods: 'use strict'; var obj = { // does not create a new scope i: 10, b: () => console.log(this.i, this), c: function() { console.log(this.i, this); } } obj.b(); // prints undefined, window {...} (or the global object) obj.c(); // prints 10, object {...} arrow functions do not have their own this.

Method definitions - JavaScript
} } generator methods generator methods can be defined using the shorthand syntax as well.
... // using a named property const obj2 = { g: function* () { let index = 0 while (true) { yield index++ } } }; // the same object using shorthand syntax const obj2 = { * g() { let index = 0 while (true) { yield index++ } } }; const it = obj2.g() console.log(it.next().value) // 0 console.log(it.next().value) // 1 async methods async methods can also be defined using the shorthand syntax.
... // using a named property const obj3 = { f: async function () { await some_promise } } // the same object using shorthand syntax const obj3 = { async f() { await some_promise } } async generator methods generator methods can also be async.
... const obj4 = { f: async function* () { yield 1 yield 2 yield 3 } }; // the same object using shorthand syntax const obj4 = { async* f() { yield 1 yield 2 yield 3 } } method definitions are not constructable methods cannot be constructors!

Functions - JavaScript
in javascript, functions are first-class objects, because they can have properties and methods just like any other object.
...see function for information on properties and methods of function objects.
... defining method functions getter and setter functions you can define getters (accessor methods) and setters (mutator methods) on any standard built-in object or user-defined object that supports the addition of new properties.
... method definition syntax starting with ecmascript 2015, you are able to define own methods in a shorter syntax, similar to the getters and setters.

Atomics - JavaScript
the atomics object provides atomic operations as static methods.
...all properties and methods of atomics are static (as is the case with the math object, for example).
... wait and notify the wait() and notify() methods are modeled on linux futexes ("fast user-space mutex") and provide ways for waiting until a certain condition becomes true and are typically used as blocking constructs.
... static methods atomics.add() adds the provided value to the existing value at the specified index of the array.

Symbol - JavaScript
the symbol() function returns a value of type symbol, has static properties that expose several members of built-in objects, has static methods that expose the global symbol registry, and resembles a built-in object class, but is incomplete as a constructor because it does not support the syntax "new symbol()".
...to create symbols available across files and even across realms (each of which has its own global scope), use the methods symbol.for() and symbol.keyfor() to set and retrieve symbols from the global symbol registry.
... static methods symbol.for(key) searches for existing symbols with the given key and returns it if found.
... instance methods symbol.prototype.tosource() returns a string containing the source of the symbol object.

TypedArray - JavaScript
on the following pages you will find common properties and methods that can be used with any typed array containing elements of any type.
... the buffer address is saved as an internal property of the instance and all the methods of %typedarray%.prototype, i.e.
... static methods typedarray.from() creates a new typedarray from an array-like or iterable object.
... instance methods typedarray.prototype.copywithin() copies a sequence of array elements within the array.

Using the WebAssembly JavaScript API - WebAssembly
this is achieved using the webassembly.compilestreaming() and webassembly.instantiatestreaming() methods.

... other notes json is purely a data format — it contains only properties, no methods.
...luckily, these two problems are so common in web development that a built-in json object is available in browsers, which contains the following two methods: parse(): accepts a json string as a parameter, and returns the corresponding javascript object.

the variable todosstatus, which we used to programmatically access the methods exposed by the todosstatus component, is of type todosstatus.
...et's see a quick example, a simple stack class that let's us push and pop elements, like this: export class stack { private elements = [] push = (element) => this.elements.push(element) pop() { if (this.elements.length === 0) throw new error('the stack is empty!') return this.elements.pop() } } in this case elements is an array of type any, and accordingly the push() and pop() methods both receive and return a variable of type any.

Assert.jsm
to use it, you first need to import the code module into your javascript scope: components.utils.import("resource://testing-common/assert.jsm"); the assert class offers methods for performing common logical assertions.
... ok, equal, notequal, deepequal, notdeepequal, strictequal, notstrictequal, throws, setreporter, report methods ok() pure assertion tests whether a value is truthy, as determined by !!guard.
... all assertion methods provide both the actual and expected values to the assertion error for display purposes.

Download
this can be done using the removepartialdata() or the finalize() methods.
... methods start() starts the download for the first time, or restarts a download that failed or has been canceled.
... note: this method should be used in place of the cancel() and removepartialdata() methods while shutting down or disposing of the download object, to prevent other callers from interfering with the operation.

Downloads.jsm
example (using task.jsm): try { yield downloads.fetch(sourceuri, targetfile); } catch (ex if ex instanceof downloads.error && ex.becausetargetfailed) { console.log("unable to write to the target file, ignoring the error."); } methods createdownload() creates a new download object.
... while some of the legacy methods and properties have an equivalent in downloads.jsm, there might be subtle differences in behavior.
...you may see the documentation of the new methods and properties for details.

XPCOMUtils.jsm
to use this, you first need to import the code module into your javascript scope: components.utils.import("resource://gre/modules/xpcomutils.jsm"); using xpcomutils exposing a javascript class as a component using these utility methods requires four key steps: import xpcomutils.jsm, as explained previously.
... methods definelazygetter() getter functions in javascript give you a way to define a property of an object, but not calculate the property's value until it is accessed.

About NSPR
additionally, nspr provides synchronization methods more suited for use by java.
...it was originally intended to export synchronous i/o methods only, relying on threads to provide the concurrency needed for complex applications.
...while the object is not declared as opaque, the api provides methods that allow and encourage clients to treat the addresses as polymorphic items.

I/O Types
prfiledesc priomethods prfileprivate prdescidentity note that the nspr documentation follows the unix convention of using the termfiles to refer to many kinds of i/o objects.
...an i/o function on a prfiledesc structure is carried out by invoking the corresponding "method" in the i/o methods table (a structure of type priomethods) of the prfiledesc structure (the "object").
... different kinds of i/o objects (such as files and sockets) have different i/o methods tables, thus implementing different behavior in response to the same i/o function call.

PR_CreateIOLayerStub
syntax #include <prio.h> prfiledesc* pr_createiolayerstub( prdescidentity ident priomethods const *methods); parameters the function has the following parameters: ident the identity to be associated with the new layer.
... methods a pointer to the priomethods structure specifying the functions for the new layer.
...the file descriptor returned contains the pointer to the i/o methods table provided.

Tracing JIT
therefore an assembler contains several machine-specific methods which are implemented in the accompanying nanojit/native*.* files.
...each define architecture-specific methods within the assembler class.
... the architecture-specific methods found in these files are the only functions within nanojit or tracemonkey that emit raw bytes of machine-code into memory.

JSClass
a c/c++ program can use a jsclass with the js_initclass and js_newobject apis to create objects that have custom methods and properties implemented in c/c++.
...instead, all the native code is in jspropertyops (property getters and setters) and jsnatives or jsfastnatives (methods).
...robot_class = { "robot", /* name */ 0 /* flags */ }; /* spidermonkey 31 or older */ static jsclass robot_class = { "robot", /* name */ 0, /* flags */ js_propertystub, js_propertystub, js_propertystub, js_propertystub, js_enumeratestub, js_resolvestub, js_convertstub, null, jsclass_no_optional_members }; to expose this class to scripts, and to attach methods and properties to it, use js_initclass.

Parser API
the expected callback methods are described under builder objects.
...builder objects may contain any of the callback methods described in this section.
...when a callback is missing, the default format is used, but the provided builder methods are still used recursively for sub-nodes.

Manipulating bookmarks using Places
the places bookmarks service, provided by the nsinavbookmarksservice interface, provides methods for creating, deleting, and manipulating bookmarks and bookmark folders.
... manipulating existing items there are a number of convenient methods you can use to make changes to existing bookmarks and bookmark folders.
... var parentfolderid = bmsvc.getfolderidforitem(newbkmkid); observing changes to bookmarks and tags to set up an observer to listen for changes related to bookmarks, you will need to create an nsinavbookmarkobserver object and use the nsinavbookmarksservice.addobserver() and nsinavbookmarksservice.removeobserver() methods.

Places Developer Guide
bookmarks the toolkit bookmarks service is nsinavbookmarksservice: var bookmarks = cc["@mozilla.org/browser/nav-bookmarks-service;1"] .getservice(ci.nsinavbookmarksservice); this service provides methods for adding, editing and deleting items in the bookmarks collection.
...placesutils.backupbookmarkstofile(jsonfile); // restore bookmarks from the json file // note: this *overwrites* all pre-existing bookmarks placesutils.restorebookmarksfromjsonfile(jsonfile); history the toolkit history service is nsinavhistoryservice: var history = cc["@mozilla.org/browser/nav-history-service;1"] .getservice(ci.nsinavhistoryservice); the history service provides methods for adding, editing, deleting browser history.
...while nsinavhistory is the main interface for history, there are a couple of other interfaces available for legacy and context-specific uses: nsibrowserhistory - detailed page addition and removal methods nsiglobalhistory2 - simple page detection and addition nsiglobalhistory3 - for adding document redirects adding to history places provides a couple of interfaces for adding to, and editing the browsing history.

Building the WebLock UI
a boolean wlocked variable can do this: // initialize the wlocked variable as unlocked var wlocked = 0; then the functions that get called from the interface and call through to the lock and unlock methods of the weblock component must also adjust this variable accordingly: function wlock() { // check to see if locking is on or off weblock.lock(); wlocked = 1; } function wunlock() { // check to see if locking is on or off weblock.unlock(); wlocked = 0; } an important preliminary of these functions is that the weblock component be made available to the javascript in the form of the w...
...in this chapter, now that we've created the weblock component and made it available to xpcom, we create the ui that actually instantiates the weblock component and uses its methods to control page loading in the browser.
...in this section, we are going to create the xul interface that calls the javascript methods when the user interacts with it.

Finishing the Component
however, some point in the future, the nsifoo interface requires a major change, and methods are reordered, some are added, others are removed.
... below, the component is compiled against a version of the nsifoo interface that has three methods.
...at the same time, you can add the macro ns_decl_nsicontentpolicy to the class declaration that provides all of the methods defined in the interface nsicontentpolicy.

How to build a binary XPCOM component using Visual Studio
that means you can call javascript methods from c++ and vice versa.
...the interface defines the methods, including arguments and return types, of the component.
...the implementation is where the methods actually do the work.

Interfacing with the XPCOM cycle collector
the traverse and unlink methods on the helper object are not magic; they are programmer-supplied and must be correct, or else the collector will fail.
...or your class may have a complicated ownership structure, such that the simple ns_impl_cycle_collection_n macros are insufficient; in this case you might need to implement the traverse and unlink methods of your helper class manually.
... manually implementing the traverse and unlink methods each field that may contain cycle collected objects needs to be passed to the cycle collector, so it can detect cycles that pass through those fields.

Components.classes
all of the properties and methods of the nsijscid and its ancestor interface nsijsid are available for use on the objects contained in this object.
... usage in order to retrieve the object for a given contractid, you can query the components.classes array as follows: var clazz0 = components.classes["@mozilla.org/messenger;1"]; clazz0 is the class object for the contractid @mozilla.org/messenger;1, which is not usually used by itself, but whose createinstance and getservice methods can be used to create a new instance of the component or to access the singleton instance, if the contract id represents a service.
... .createinstance(components.interfaces.nsisupportsarray); which is a shortcut to var obj = components.classes["@mozilla.org/supports-array;1"] .createinstance(); obj.queryinterface(components.interfaces.nsisupportsarray); if you don't provide a specific interface to createinstance(), it will return an xpconnect wrapper for the component, which only exposes the methods of the nsisupports interface (and under certain circumstances the special wrappedjsobject property).

Language bindings
more specifically, an xpcom language binding: enables access to xpcom objects from that language (where access means reading/writing/creating xpcom objects as well as calling methods on them).
...the scriptable methods on the nsicomponentmanager interface can be called directly on this object.components.resultscomponents.results is a read-only object whose properties are the names listed as the first parameters of the macros in js/xpconnect/src/xpc.msg (also at table of errors), with the value of each corresponding to that constant's value.components.returncodecomponents.stackcomponents.stack is a read only pro...
...any expando properties are not visible, and if any native properties have been redefined, this has no effect.components.utils.makeobjectpropsnormalensures that the specified object's methods are all in the object's scope, and aren't cross-component wrappers.components.utils.reporterrorcomponents.utils.reporterror reports a javascript error object to the error console, and returns.

port - Archive of obsolete content
port methods emit() the port.emit() function sends a message from one side to the other.
...this means you can't send functions, and if the object contains methods they won't be encoded.

Classes and Inheritance - Archive of obsolete content
we will show how to make inheritance work correctly with respect to constructors, prototypes, and the instanceof operator, and how to override methods in subclasses.
...the constructor property is supposed to be non-configurable, non-enumberable, and non-writable, so the correct way to define it is as follows: circle.prototype = object.create(shape.prototype, { constructor: { value: circle } }); overriding methods as a final example, we show how to override the stub implementation of the method draw in shape with a more specialized one in circle.

Content Processes - Archive of obsolete content
each event emitter has several methods: the method on is used to add a listener for an event.
...a potential problem with the content script having access to the window object is that a malicious page could override methods on the window object that it knows are being used by the add-on, in order to trick the add-on into doing something it does not expect.

Modules - Archive of obsolete content
the problem with breaking encapsulation like this is that malicious scripts can use it to get the loading script to execute arbitrary code, by overriding one of the methods on the built-in constructors.
... if the loading script has chrome privileges, then so will any methods called by the loading script, even if that method was installed by a malicious script.

page-mod - Archive of obsolete content
this means you can't send functions, and if the object contains methods they won't be usable.
... methods destroy() stops the page-mod from making any more modifications.
