NodeReferenceCount
from panda3d.core import NodeReferenceCount
- class NodeReferenceCount
Bases:
ReferenceCount
This class specializes ReferenceCount to add an additional counter, called node_ref_count, for the purposes of counting the number of times the object is referenced by a “node”, whatever that may mean in context.
The new methods node_ref() and node_unref() automatically increment and decrement the primary reference count as well. There also exists a NodePointerTo<> class to maintain the node_ref counters automatically.
See also CachedTypedWritableReferenceCount, which is similar in principle, as well as NodeCachedReferenceCount, which combines both of these.
