clear()

template<class ObjectType , class ReferenceCountingType = ReferenceCountedObject>

void WeakReference< ObjectType, ReferenceCountingType >::Master::clear ( )

noexcept

The object that owns this master pointer should call this before it gets destroyed, to zero all the references to this object that may be out there.

See the WeakReference class notes for an example of how to do this.

getNumActiveWeakReferences()

template<class ObjectType , class ReferenceCountingType = ReferenceCountedObject>

int WeakReference< ObjectType, ReferenceCountingType >::Master::getNumActiveWeakReferences ( ) const

noexcept

Returns the number of WeakReferences that are out there pointing to this object.
