Class DataNodeVetoAdapter

java.lang.Object
  com.ibm.commons.iloader.node.DataNodeVetoAdapter

All Implemented Interfaces:

DataNodeVetoListener

public abstract class DataNodeVetoAdapter
extends java.lang.Object
implements DataNodeVetoListener

A default adapter for the com.ibm.commons.iloader.node.DataNodeVetoListener interface. Allows clients to selectively veto certain events rather than needing to implement the entire listener interface. This default implementation returns true for all queries.
