/**
* @class vtkWeakPointerBase
* @brief Non-templated superclass for vtkWeakPointer.
*
* vtkWeakPointerBase holds a pointer to a vtkObjectBase or subclass
* instance, but it never affects the reference count of the vtkObjectBase. However,
* when the vtkObjectBase referred to is destroyed, the pointer gets initialized to
* NULL, thus avoid dangling references.
