Class GroovyMBean

java.lang.Object
  groovy.lang.GroovyObjectSupport
      groovy.util.GroovyMBean

All Implemented Interfaces:

GroovyObject

public class GroovyMBean
extends GroovyObjectSupport

A GroovyObject facade for an underlying MBean which acts like a normal groovy object but which is actually implemented via an underlying JMX MBean. Properties and normal method invocations delegate to the MBeanServer to the actual MBean.
