Inheritance diagram for nsIWeakReference:

nsISupports nsJavaXPTCStubWeakRef

List of all members.

Detailed Description

An instance of |nsIWeakReference| is a proxy object that cooperates with its referent to give clients a non-owning, non-dangling reference. Clients own the proxy, and should generally manage it with an |nsCOMPtr| (see the type |nsWeakPtr| for a |typedef| name that stands out) as they would any other XPCOM object. The |QueryReferent| member function provides a (hopefully short-lived) owning reference on demand, through which clients can get useful access to the referent, while it still exists.
