Class RecursionCutoffPoint

java.lang.Object

org.eclipse.viatra.query.runtime.rete.construction.plancompiler.RecursionCutoffPoint

public class RecursionCutoffPoint
extends java.lang.Object

In a recursive query structure, query composition references can be cut off so that the remaining structure is DAG. RecursionCutoffPoint represents one such cut off query composition. When the compilation of the recursive query finishes and the compiled form becomes available, the RecursionCutoffPoint has to be signaled to update parent traces and recipes of the recursive call.
