Class DestinationValidator

java.lang.Object
  nodenet.registrar.DestinationValidator

All Implemented Interfaces:

java.util.EventListener, java.io.Serializable, java.beans.VetoableChangeListener

public class DestinationValidator

extends java.lang.Object

implements java.beans.VetoableChangeListener, java.io.Serializable

A quick implementation of a class that validates destination values for NodeConfigurationBeans. It is a singleton class of which there should never be more than one instance. FIXME: This should be broken out to a strategy pattern similar to the NodeNameRegistry class. This class is not in current use but may be used in future versions.
