Subclass of QmfManaged to provide a Console specific representation of management data.
The Console application represents a managed data object by the QmfConsoleData class. The Console has "read only" access to the data values in the data object via this class. The Console can also invoke the methods defined by the object via this class.
The actual data stored in this object is cached from the Agent. In order to update the cached values, the Console invokes the instance's refresh() method.
Note that the refresh() and invokeMethod() methods require communication with the remote Agent. As such, they may block. For these two methods, the Console has the option of blocking in the call until the call completes. Optionally, the Console can receive a notification asynchronously when the operation is complete.
