/**
* Utilities for JavaScript components loaded by the JS component
* loader.
*
* Import into a JS component using
* 'Components.utils.import("resource://gre/modules/XPCOMUtils.jsm");'
*
* Exposing a JS 'class' as a component using these utility methods consists
* of several steps:
* 0. Import XPCOMUtils, as described above.
* 1. Declare the 'class' (or multiple classes) implementing the component(s):
* function MyComponent() {
* // constructor
* }
* MyComponent.prototype = {
* // properties required for XPCOM registration:
* classDescription: "unique text description",
* classID: Components.ID("{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}"),
* contractID: "@example.com/xxx;1",
*
* // [optional] custom factory (an object implementing nsIFactory). If not
* // provided, the default factory is used, which returns
* // |(new MyComponent()).QueryInterface(iid)| in its createInstance().
* _xpcom_factory: { ... },
*
* // [optional] an array of categories to register this component in.
* _xpcom_categories: [{
* // Each object in the array specifies the parameters to pass to
* // nsICategoryManager.addCategoryEntry(). 'true' is passed for
* // both aPersist and aReplace params.
* category: "some-category",
* // optional, defaults to the object's classDescription
* entry: "entry name",
* // optional, defaults to the object's contractID (unless
* // 'service' is specified)
* value: "...",
* // optional, defaults to false. When set to true, and only if 'value'
* // is not specified, the concatenation of the string "service," and the
* // object's contractID is passed as aValue parameter of addCategoryEntry.
* service: true
* }],
*
* // QueryInterface implementation, e.g. using the generateQI helper
* QueryInterface: XPCOMUtils.generateQI(
* [Components.interfaces.nsIObserver,
* Components.interfaces.nsIMyInterface]),
*
* // ...component implementation...
* };
*
* 2. Create an array of component constructors (like the one
* created in step 1):
* var components = [MyComponent];
*
* 3. Define the NSGetModule entry point:
* function NSGetModule(compMgr, fileSpec) {
* // components is the array created in step 2.
* return XPCOMUtils.generateModule(components);
* }
*/
