Class MultiEventHandler

java.lang.Object
  net.sf.basedb.util.bfs.MultiEventHandler

All Implemented Interfaces:

EventHandler

public class MultiEventHandler
extends Object
implements EventHandler

Event handler implementation that forwards a single event to multiple event handlers. This is useful since a parser only sends the event to a single handler. The event is forwarded to all registered event handlers in the order they have been registered.
