Detailed Description

An Abstract Base class for the hooks in the ORB.

This class (would) define all the hooks that may be needed by the ORB to override some of its default behaviour. The methods can be potentially used to call service level specific processing that may be required.

[virtual]

Check whether obj is nil or not.
