Summary
Inherit from this C++ class to add canonical support for nsISupportsWeakReference
.
See Weak reference for detailed description of weak references.
#include "nsWeakReference.h" class nsSupportsWeakReference { ... };
Remarks
In addition to inheriting from this class, you will need to ensure that your nsISupports::QueryInterface
implementation exposes nsISupportsWeakReference
as a supported interface.
To use this class, you must link your component or application against the XPCOM Glue library.
Example code
// Supporting weak references to a hypothetical implementation // of the nsIFoo interface... #include "nsWeakReference.h" #include "nsIFoo.h" class MyFoo : public nsIFoo, public nsSupportsWeakReference { public: NS_DECL_ISUPPORTS NS_DECL_NSIFOO ... }; NS_IMPL_ISUPPORTS2(MyFoo, nsIFoo, nsISupportsWeakReference) ...
