class TAO_LB_Replica_Equal_To
{
  // = TITLE
  //     Function object for comparing equivalence of two Replica
  //     references.
  //
  // = DESCRIPTION
  //     This class basically wraps the
  //     CORBA::Object::_is_equivalent() method so that it can be
  //     utilized by a Hash Map to determine equivalence of two
  //     external IDs.

public:

  int operator() (const CORBA::Object_ptr &lhs,
                  const CORBA::Object_ptr &rhs) const;
  // 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.

class TAO_LB_Location_Equal_To
{
  // = TITLE
  //     Function object for comparing equivalence of two Locations
  //
  // = DESCRIPTION
  //     This class iterates through the contents of the two Locations
  //     being compared.  If any of the corresponding contents of the
  //     Locations do not match, then the Locations are not equal.

public:

  int operator() (const TAO_PortableGroup::Location &lhs,

  // Iterate through the contents of each Location until a mismatch
  // occurs.  If no mismatch is found, then the Locations are
  // considered equal.
