Returns true if the MBean specified is an instance of the specified class, false otherwise.

Parameters:

name - The object name of the MBean to be checked.

className - The name of the class.

Returns:

true if the MBean is the instance of the specified class, false otherwise.

Throws:

registerMBean

javax.management.ObjectInstance registerMBean(java.lang.Object object,
                                              javax.management.ObjectName name)

name - The object name of the MBean. May be null.

Returns:

The ObjectInstance for the MBean that has been registered.

Throws:
