## Detailed Description

### template<class HANDLER1, class HANDLER2>
class Tuples::detail::TupleObjImp< HANDLER1, HANDLER2 >

The simplest concrete implementation of class TupleObj with 3 arbitrary error handlers Any types (classes, functions, etc.

) which supports the semantics

         HANDLER obj = .. ;

         StatusCode obj( msg , sc )

can be used as error handler, e.g.

       void print_error   ( const std::string& msg , StatusCode sc )
        { std::cout <<
          "Error"   << msg << " code " << sc.getCode() << std::endl ; }
       void print_warning ( const std::string& msg , StatusCode sc )
        { std::cout <<
          "Warning" << msg << " code " << sc.getCode() << std::endl ; }
       void print_print   ( const std::string& msg , StatusCode sc )
        { std::cout << msg << " code " << sc.getCode() << std::endl ; }

       NTuple::Tuple* tuple = ... ;
       TupleObj* obj =
        createTupleObj( print_errror   ,
                        print_warning  ,
                        print_print    ,
                        " my tuple "   , ntuple ) ;

Templated helper functions allow to avoid heavy semantics of dealing with explicit type

Few concrete error handlers for dealing with classes, which supports member functions Error and Warning ( e.g. class GaudiAlgorithm or class GaudiTool ) are provided
