...getclassobject() obtains a class object from a nsimodule for a given cid and iid pair.
... registerself() when the nsimodule is discovered, this method will be called so that any setup registration can be preformed.

Creating the Component Code
specifically, the component library has to contain implementations for the component-related interfaces described in this chapter: nsimodule and nsifactory, which are entry points for your implementation code.
... moving another layer outward is the nsimodule.
...instead, the nsimodule can ask for implementation details about the xpcom object.

Component Internals
as a component in the xpcom framework illustrates, in addition to the nsgetmodule entry point, there are nsimodule and nsifactory interfaces that control the actual creation of the component, and also the string and xpcom glue parts, which we'll discuss in some detail in the next section (see xpcom glue).
...this loader is responsible for initialization, loading, unloading, and supporting the nsimodule interface on behalf of each component.
...the module layer is represented by the nsimodule interface.

Starting WebLock
the first callback is called when the component's nsimodule::registerself method is called.
...these are also parameters in the nsimodule implementation in xxx what is example 1?
...weblock has already implemented the nsisupports, nsifactory, nsimodule, and nsiobserver interfaces that handle generic component functionality including being initialized at startup.

nsGetModuleProc

Using XPCOM Utilities to Make Things Easier
the module macros include one set of macros that define the exported nsgetmodule entry point, the required nsimodule implementation code and another that creates a generic factory for your implementation class.
... xpcom module macros macro description ns_impl_nsgetmodule(name, components) implements the nsimodule interface with the module name of name and the component list in components.

A bird's-eye view of the Mozilla framework
likewise, an xpcom component must implement nsifactory, which provides a mechanism for creating an object without having access to the class declaration for that object, nsimodule, which provides a mechanism for registering and unregistering the xpcom component, as well as for accessing the underlying class objects implementing the idl interfaces, and nsgetmodule(), the entry point used to load the xpcom component.
