// Class : NodePointerToBase
|
|
// Description : 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.
