Package groovy.jmx

## Class GroovyMBean

- java.lang.Object
- - groovy.lang.GroovyObjectSupport
  - - groovy.jmx.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.
