org.mozilla.interfaces.nsIInterfaceRequestor

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. @status FROZEN
