Class MBeanIntrospector

java.lang.Object

mx4j.server.MBeanIntrospector

public class MBeanIntrospector
extends java.lang.Object

Introspector for MBeans.

Main purposes of this class are:

• Given an mbean, gather all information regarding it into a MBeanMetaData instance, see introspect(mx4j.server.MBeanMetaData)
• Given an introspected MBeanMetaData, decide if the MBean is compliant or not.
• Act as a factory for MBeanInvokers

The following system properties are used to control this class' behavior:

• mx4j.strict.mbean.interface, if set to 'no' then are treated as standard MBeans also classes that implement management interfaces beloging to different packages or that are inner classes; otherwise are treated as MBeans only classes that implement interfaces whose name if the fully qualified name of the MBean class + "MBean"
• mx4j.mbean.invoker, if set to the qualified name of an implementation of the MBeanInvoker interface, then an instance of the class will be used to invoke methods on standard MBeans. By default the generated-on-the-fly MBeanInvoker is used; to revert to the version that uses reflection, for example, use mx4j.mbean.invoker = mx4j.server.CachingReflectionMBeanInvoker
