  // = TITLE
  //     Function object that compares equality of two ObjectGroup
  //     references.
  //
  // = DESCRIPTION
  //     This class basically wraps the
  //     CORBA::Object::_is_equivalent() method so that it can be
  //     utilized by a Hash Map as a way to compare equality.

  int operator() (const TAO_LoadBalancing::ObjectGroup_ptr &lhs,

  // Invokes the CORBA::Object::_is_equivalent() method to determine
  // if both references refer to the same object group.  However, this
  // is a weak test since is_equivalent() can only conclusively
  // determine if two references refer to the same object, but it
  // cannot determine if two refereneces do not refer to the same
  // object.
