  org.progeeks.graph.LoggingGraph

All Implemented Interfaces:

com.phoenixst.plexus.Graph

public class LoggingGraph
extends java.lang.Object
implements com.phoenixst.plexus.Graph

A graph useful for debugging as it simply logs all method requests with their parameters but otherwise performs no-ops.
