Interface GoalChecker<Node>

Type Parameters:
Node - Type representing nodes in the search tree.
All Superinterfaces:
Predicate<Node>
public interface GoalChecker<Node>
extends Predicate<Node>
Methods required of objects which check that a tree node corresponds to a search goal. This interface extends a Predicate, and its check method does correspond to checking each node as it is removed from the frontier for expansion. However these object can also allow the search process to delay selecting the found node until the end of a complete search; in this usage the get method should return the desired search result.
