Class MBeanResolver

java.lang.Object
  org.jmx4odp.j4oNet.MBeanResolver

All Implemented Interfaces:

javax.management.MBeanRegistration, MBeanResolverMBean

Direct Known Subclasses:

BroadcastResolver, JsResgistryResolver, MBeanServerResolver

public abstract class MBeanResolver
extends java.lang.Object
implements javax.management.MBeanRegistration, MBeanResolverMBean

Extend this abstract class to create a custom MBeanResolver. It contains the basic functictions such as detrming if a request is in range and the basic attributes such as cachable, active, etc.

Specifically, coders need to override the handleMBeanRequest and handleAgentRequest methods. If a resolution request is with in range, and the MBean is active, it will pass the JmxServiceObj to one of these methods, depending on the JmxServiceObj.isAgent() method.

Method Detail

resolve

public JmxServiceObj[] resolve(JmxServiceObj jso,
                               int low,
                               int high)

if the threshHold is not lower than low or higher or than high and the bean is active, and the jso is inNameSpace, then it will call handleRequest, else it returns a null

Specified by:

resolve in interface MBeanResolverMBean

inNameSpace

protected boolean inNameSpace(JmxServiceObj jso)

if the jso is null, it returns a false. if the jso.getNameSpace is null, it returns a true. if the jso name space is "DEFAULT", it returns a true jso name space is the reolver's name space, or a child of it, it returns a true. else it returns a false

handleMBeanRequest

protected JmxServiceObj[] handleMBeanRequest(JmxServiceObj jso)

this is what all the children MBeanResolvers should over write.

handleAgentRequest

protected JmxServiceObj[] handleAgentRequest(JmxServiceObj jso)

registered

protected void registered(javax.management.MBeanServer mBeanServer,
                          javax.management.ObjectName obj)

This is a preRegistration call out if any special behavior is needed and the developer doesn't want to over write preRegistration
