/**
* @class TAO_Object_Ref_Table
*
* @brief Keep a table de-stringified object references registered
* with the ORB.
*
* The class is necessary to allow local objects to be accessible via
* the resolve_initial_references() mechanism. Since local object
* references cannot be stringified, they cannot be placed into the
* initial reference map that maps object key/name to stringified
* object reference. Hence, another table is needed.
*
* @note
* The stringified reference table is still needed since it is
* sometimes necessary to delay de-stringification of an IOR until it
* is needed. For example, "corbaname" may return different results
* on each use.
