some of it like the section on building the index and usage tips are still relevant, and other parts still may provide useful background information to understand it in more detail on how eclipse works.
... to be able to provide really good code assistance for a project's source code, ides like eclipse need to carry out a thorough static analysis of the project's source files, to build up a picture of the code (what eclipse is trying to do when it "indexes" the source.) static analysis involves parsing the source files, so naturally it can only produce good results if it has a sensible set of preprocessor defines, include paths and pre-include files for each source file.
...versely, note this very carefully: if you configure eclipse to invoke a build process that is parallelized, silenced, or that fails to identify the directory that the compiler is being run from, then it will mess up the compiler options that eclipse associates with your files, and that in turn will significantly degrade the quality of the code assistance that eclipse will provide after it next re-indexes the code.

Square tilemaps implementation: Static maps - Game development
gettile(): a helper method that gets the tile index in a certain position.
...0 for the left-most tile.) however, we must account for empty tiles, since they are crucial for implementing layers — empty tiles are usually assigned a negative index value, 0, or a null value.
... in these examples, empty tiles will be represented by index 0, so we will shift the indices of the atlases by one (and thus the first tile of the atlas will be assigned index 1, the second index 2, etc.) the gettile() helper method returns the tile contained at the specified column and row.
...in this case, we need to map the column and row to an array index: var index = row * map.cols + column; wrapping up, an example of a tilemap object could look like the following.

... ns_imethod getinterfaceinfo(nsiinterfaceinfo** info) = 0; // call this method and return result ns_imethod callmethod(pruint16 methodindex, const nsxptmethodinfo* info, nsxptcminivariant* params) = 0; }; code that wishes to make use of this stubs functionality (such as xpconnect) implement a class which inherits from nsxptcstubbase and implements the getinterfaceinfo and callmethod to let the platform specific code know how to get interface information and how to dispatch methods ...
...xptcall/tests has an api level test for ns_invokebyindex, but no tests for the stubs functionality.

CSSValueList.item() - Web APIs
the item() method of the cssvaluelist interface is used to retrieve a cssvalue by ordinal index.
...if the index is greater than or equal to the number of values in the list, this method returns null.

Introduction to the DOM - Web APIs
items in a nodelist are accessed by index in either of two ways: list.item(1) list[1] these two are equivalent.
... namednodemap a namednodemap is like an array, but the items are accessed by name or index, though this latter case is merely a convenience for enumeration, as they are in no particular order in the list.
... <html> <head> <title>dom tests</title> <script> function setbodyattr(attr, value) { if (document.body) document.body[attr] = value; else throw new error("no support"); } </script> </head> <body> <div style="margin: .5in; height: 400px;"> <p><b><tt>text</tt></b></p> <form> <select onchange="setbodyattr('text', this.options[this.selectedindex].value);"> <option value="black">black</option> <option value="red">red</option> </select> <p><b><tt>bgcolor</tt></b></p> <select onchange="setbodyattr('bgcolor', this.options[this.selectedindex].value);"> <option value="white">white</option> <option value="lightgrey">gray</option> </select> <p><b><tt>link</tt></b></p> <s...

FileHandle API - Web APIs
basic operations create a filehandle because the intent is to allow the storage of files through indexeddb, creating a filehandle instance requires an indexeddb database.
... var idbreq = indexeddb.open("myfilestoragedatabase"); idbreq.onsuccess = function(){ var db = this.result; var buildhandle = db.mozcreatefilehandle("test.txt", "plain/text"); buildhandle.onsuccess = function(){ var myfilehandle = this.result; console.log('handle', myfilehandle); }; }; mozcreatefilehandle() takes two arguments: a name and an optional type.

HTMLCollection.item - Web APIs
note: because the contents of an htmlcollection are live, changes to the underlying dom can and will cause the position of individual nodes in the collection to change, so the index value will not necessarily remain constant for a given node.
... syntax var element = htmlcollection.item(index) parameters index the position of the node to be returned.
... return value the node at the specified index, or null if index is less than zero or greater than or equal to the length property.
...in javascript, it is easier to treat the htmlcollection as an array and to index it using array notation.

HTMLInputElement.setSelectionRange() - Web APIs
selectionstart the 0-based index of the first selected character.
... an index greater than the length of the element's value is treated as pointing to the end of the value.

IDBFactory.deleteDatabase() - Web APIs
syntax for the current standard: var request = indexeddb.deletedatabase(name); for the experimental version with options (see below): var request = indexeddb.deletedatabase(name, options); parameters name the name of the database you want to delete.
... optionsnon-standard in gecko, since version 26, you can include a non-standard optional storage parameter that specifies whether you want to delete a permanent (the default value) indexeddb, or an indexeddb in temporary storage (aka shared pool.) return value a idbopendbrequest on which subsequent events related to this request are fired.
... example var dbdeleterequest = window.indexeddb.deletedatabase("todolist"); dbdeleterequest.onerror = function(event) { console.log("error deleting database."); }; dbdeleterequest.onsuccess = function(event) { console.log("database deleted successfully"); console.log(event.result); // should be undefined }; specifications specification status comment indexed database api draftthe definition of 'deletedatabase()' in that specification.

IDBLocaleAwareKeyRange - Web APIs
the idblocaleawarekeyrange interface of the indexeddb api is a firefox-specific version of idbkeyrange — it functions in exactly the same fashion, and has the same properties and methods, but it is intended for use with idbindex objects when the original index had a locale value specified upon its creation (see createindex()'s optionalparameters) — that is, it has locale aware sorting enabled.
...with locale-aware indexes, the meaning of < depends on the locale, so for example in lithuanian y is sorted between i and k.
... developers should always use idblocaleawarekeyrange when dealing with locale-aware indexes.
... examples function displaydata() { var keyrangevalue = idblocaleawarekeyrange.bound("a", "f"); var transaction = db.transaction(['fthings'], 'readonly'); var objectstore = transaction.objectstore('fthings'); var myindex = objectstore.index('lname'); myindex.opencursor(keyrangevalue).onsuccess = function(event) { var cursor = event.target.result; if(cursor) { var tablerow = document.createelement('tr'); tablerow.innerhtml = '&lt;td&gt;' + cursor.value.id + '&lt;/td&gt;' + '&lt;td&gt;' + cursor.value.lname + '&lt;/td&gt;' + '&lt;td&gt;' + cursor.value.fname + '&lt;/td&gt;' + '&lt;td&gt;' + cursor.value.jtitle + '&lt;/td&gt;' + '&lt;td&gt;' + cursor.value.
