//  The classes derived from this object are normally used to apply an
//  operation to all objects in the OPAL directory.  This is done by calling
//  Directory::apply(functor).  The functor itself takes a pointer to an
//  object as an argument, and defines an operator with the signature
//  [tt]void operator()(Object *)[/tt] which performs that operation.
