Detailed Description

template<class T>
class NodePointerToBase< T >

This is similar to PointerToBase, but it manages objects of type NodeReferenceCount or NodeCachedReferenceCount, and it updates the node_ref_count instead of the regular ref_count.

It is intended for use only in PandaNode, to hold a pointer to RenderState and TransformState, although it could be used by any object that wanted to maintain a separate reference count for reporting purposes.

Member Function Documentation

template<class T >
void NodePointerToBase< T >::clear ( ) [inline]

A convenient way to set the NodePointerTo object to NULL.

(Assignment to a NULL pointer also works, of course.)

Definition at line 113 of file nodePointerToBase.I.

template<class T >
void NodePointerToBase< T >::output ( ostream &  out) const [inline]

A handy function to output NodePointerTo's as a hex pointer followed by a reference count.

Definition at line 125 of file nodePointerToBase.I.

template<class T >
void NodePointerToBase< T >::reassign ( To *  ptr) [protected]

This is the main work of the NodePointerTo family.

When the pointer is reassigned, decrement the old reference count and increment the new one.

Definition at line 58 of file nodePointerToBase.I.
