Class AbstractMarkerBean

java.lang.Object

com.kdgregory.logging.aws.internal.AbstractMarkerBean

All Implemented Interfaces:

DynamicMBean, MBeanRegistration

public abstract class AbstractMarkerBean
extends Object
implements DynamicMBean, MBeanRegistration

This class serves as the base "marker bean" for JMX integration: it implements the MBean interfaces, and acts as a listener for registration and deregistration notifications. Subclasses implement the behavior for these notifications, typically by registering or deregistering with a framework-specific subclass of AbstractJMXManager.
