public class PlaceNode
extends LocalNodeWithExternalizedLogic<Place,PlaceState,PlaceNode>

This class represents a tree node containing a Place (as NodeProperties) together with a PlaceState (as NodeState) that indicates already generated children nodes. It is an implementation of a GeneratingLocalNode, that is, it does not hold references to any other nodes and instead employs only its local state and a PlaceGenerator to compute unseen children.
