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)
...
