/**
|
|
* The nsIInterfaceRequestor interface defines a generic interface for
|
|
* requesting interfaces that a given object might provide access to.
|
|
* This is very similar to QueryInterface found in nsISupports.
|
|
* The main difference is that interfaces returned from GetInterface()
|
|
* are not required to provide a way back to the object implementing this
|
|
* interface. The semantics of QI() dictate that given an interface A that
|
|
* you QI() on to get to interface B, you must be able to QI on B to get back
|
|
* to A. This interface however allows you to obtain an interface C from A
|
|
* that may or most likely will not have the ability to get back to A.
