  sofya.apps.dejavu.EdgeSelector.EdgeTraversal

Enclosing class:

EdgeSelector

public static class EdgeSelector.EdgeTraversal
extends java.lang.Object

Data container class which is used to direct the behavior of the graph traverser.

Constructor Summary

protected	EdgeSelector.EdgeTraversal() Creates a traversal instruction which directs the graph traverser to follow all outgoing edges.
protected	EdgeSelector.EdgeTraversal(Node oldSuccessor, Node newSuccessor) Creates a traversal instruction with directs the graph traverser to proceed to a particular successor.

Method Summary

Node	newSuccessor() Gets the next node in the new graph to which the traversal should proceed.
Node	oldSuccessor() Gets the next node in the old graph to which the traversal should proceed.
boolean	traverseAll() Reports whether the graph traverser should follow all outgoing edges.
