from panda3d.core import WorkingNodePath
This is a class designed to support low-overhead traversals of the complete scene graph, with a memory of the complete path through the graph at any given point.
You could just use a regular NodePath to do this, but since the NodePath requires storing NodePathComponents on each node as it is constructed, and then removing them when it destructs, there is considerable overhead in that approach.
The WorkingNodePath eliminates this overhead (but does not guarantee consistency if the scene graph changes while the path is held).
At any given point, you may ask the WorkingNodePath for its actual NodePath, and it will construct and return a new NodePath representing the complete generated chain.
Returns true if the WorkingNodePath object appears to be a valid NodePath reference, false otherwise.
