nsIJSID

This interface provides information about a contract or interface.
Inherits from: nsISupports Last changed in Gecko 1.9 (Firefox 3)

The following methods return objects that implement this interface:

Components.interfaces.name
Components.classes[contract]
Components.interfacesById[uuid]
Components.classesById[cid]

The first two cases create a named JSID while the last two cases create an unnamed JSID. An unnamed JSID also results when you implement a function that is passed an nsIIDRef parameter, such as QueryInterface(). Note that for these cases of JSID the specified class or interface must exist and be scriptable.
