Detailed Description

Guard implementation used to make object group cleanup exception-safe.

This guard's destructor performs cleanup of object group resources. Thus, cleanup is performed when this guard goes out of scope unless explicitly released from that responsibility.

This guard is meant to be used internally by the TAO_PG_GenericFactory class.
