Class SpyPoints

java.lang.Object

org.projog.core.event.SpyPoints

public final class SpyPoints
extends Object

Collection of spy points.

Spy points are useful in the debugging of Prolog programs. When a spy point is set on a predicate a SpyPoints.SpyPointEvent is generated every time the predicate is executed, fails or succeeds.

Each KnowledgeBase has a single unique SpyPoints instance.
