## Member Function Documentation

const InterfaceID & ITupleTool::interfaceID | ( |  | ) | `[static]`

Return the unique interface ID.

Reimplemented from IAlgTool.

virtual Tuple ITupleTool::nTuple | ( | const std::string & | title,
|  | const CLID & | clid = `CLID_ColumnWiseTuple` |
| ) |  |  | const`[pure virtual]`

get N-tuple object ( book on-demand ) with unique identidier

      ITupleTool* tool = .. ;
      Tuple tuple = tool->nTuple( 'My tuple' ) ;
      tuple->column( "A" , sin(0.1) );
      tuple->column( "B" , cos(0.1) );
      tuple->column( "C" , tan(0.1) );
      tuple->write()

NTuple will be booked with automatically assigned numerical ID

Parameters:

  | title | unique title for ntuple
  | clid | class identifier

Returns:
  ntuple object
