org.jboss.mx.remoting.event
Class ClassQueryExp

java.lang.Object
  extended byorg.jboss.mx.remoting.event.ClassQueryExp
All Implemented Interfaces:
QueryExp (src) , java.io.Serializable
public class ClassQueryExp
extends java.lang.Object
implements QueryExp (src) , java.io.Serializable

ClassQueryExp is a QueryExp implementation that allows you to check the ObjectName on a query against one or more class names to make sure that they are the instanceof one or more classes.

Example code: 

   ClassQueryExp query=new ClassQueryExp(MyMBean.class);
   Set beans=mbeanserver.queryMBeans(new ObjectName("*:*"),query);
The query in the above example will only return MBean ObjectInstances that are an instanceof MyMBean class.
