# PointerToVoid

from pandac.PandaModules import PointerToVoid

Class : PointerToVoid
Description : 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 ReferenceCount object, to implement weak reference pointers--we need to have something to clean up when the ReferenceCount object destructs.
This is the base class for PointerToBase<T>.
