Detailed Description

ObserverNodePath is an observer class for tracking changes to a NodePath, that automatically invalidates it when nodes are deleted.

const

Get a lightweight NodePath that isn't thread safe but may be safely used in single threaded applications, or when its known that the NodePath won't be invalidated during usage of the NodePath. return true if NodePath is valid.

const

Get a thread safe RefNodePath, return true if NodePath is valid.
