All Implemented Interfaces:

public class ModelMBeanOperationInfo

extends MBeanOperationInfo

implements DescriptorAccess

The ModelMBeanOperationInfo object describes a management operation of the ModelMBean. It is a subclass of MBeanOperationInfo with the addition of an associated Descriptor and an implementation of the DescriptorAccess interface.

 The fields in the descriptor are defined, but not limited to, the following:
 name           : operation name
 descriptorType : must be "operation"
 class          : class where method is defined (fully qualified)
 role           : getter, setter, operation, constructor
 targetObject   : object on which to execute this method
 targetType     : type of object reference for targetObject:
                  ObjectReference|EJBHandle|IOR|RMIReference
 lastReturnedValue : cached value for operation
 currencyTimeLimit : how long cached value is valid
 lastReturnedTimeStamp : when cached value was set
 visibility            : 1-4 where 1: always visible 4: rarely visible
 presentationString :  xml formatted string to describe how to present operation
 

The default descriptor will have name, descriptorType, and role fields set.
