This is the non-template part of the base class for PointerTo and ConstPointerTo. It is necessary so we can keep a pointer to a non-template class within the
ReferenceCountobject, to implement weak reference pointers–we need to have something to clean up when the
This is the base class for PointerToBase<T>.
getHash() → size_t¶
- Return type
isNull() → bool¶
Returns true if the PointerTo is a NULL pointer, false otherwise. (Direct comparison to a NULL pointer also works.)
