template<class PBASE >

Tuples::Tuple GaudiTuples< PBASE >::evtCol	(	const std::string &	title,
		const CLID &	clid = CLID_ColumnWiseTuple
	)		const

Access an Event Tag Collection object (book on-demand) with unique identifier.

Tuple tuple = evtCol( "My Tag Collection" ) ;
tuple->column( "A" , sin(0.1) );
tuple->column( "B" , cos(0.1) );
tuple->column( "C" , tan(0.1) );
tuple->write();

The Event Tag Collection will get a unique identifier automatically assigned which by default will be equal to the histogram title. An option exists to instead use numerical IDs. In this case the first Event Tag Collection booked will be ID=1 the next ID=2 and so on. Note though this scheme is not recommended as it does NOT guarantee predictability of the ID a given Event Tag Collection will be given when filled under conditional statements, since in these circumstances the order in which the Event Tag Collection are first filled, and thus booked, will depend on the nature of the first few events read. This is particularly problematic when users submit many parallel 'sub-jobs' and then attempt to merge the final output ROOT (or HBOOK) files, since a given Event Tag Collection could have different IDs in each of the sub-jobs. Consequently it is strongly recommended that users do not use numerical automatic IDs unless they are sure they understand what they are doing.

Parameters

title	Unique title for Event Tag Collection
clid	N-Tuple class identifier (row or column wise)

Returns

ntuple The Event Tag Collection object

Tuples::Tuple GaudiTuples< PBASE >::evtCol	(	const TupleID &	ID,
		const std::string &	title,
		const CLID &	clid = CLID_ColumnWiseTuple
	)		const

Access an Event Tag Collection object (book on-demand) with forced identifier.

// Book Ntuple with a numeric ID
Tuple tuple = evtCol(  1,  "My Tag Collection" ) ;
// ... or
Tuple tuple = evtCol( "1", "My Tag Collection" ) ;

// ... or, Book Ntuple with a literal ID
Tuple tuple = evtCol( "mytuple", "My Tag Collection" ) ;

// ... or, Book Ntuple with a literal ID in a sub-dir
Tuple tuple = evtCol( "subdir/mytuple", "My Tag Collection" ) ;

// Fill and write
tuple->column( "A" , sin(0.1) );
tuple->column( "B" , cos(0.1) );
tuple->column( "C" , tan(0.1) );
tuple->write();

Attention

If the Event Tag Collection with given ID is already booked through automatic assignment of Event Tag Collection ID, the error will not be detected. Therefore it is recommended to use a non-trivial Event Tag Collection ID offset (property "EvtColOffSet") if one need to combine these techniques together It is still desirable to use the unique Event Tag Collection title to avoid a bad interference.

Parameters

ID	The forced Event Tag Collection ID
title	Unique title for Event Tag Collection
clid	N-Tuple class identifier (row or column wise)

Returns

ntuple The Event Tag Collection object

// Book Ntuple with a numeric ID
Tuple tuple = nTuple(  1,  "My tuple" ) ;
// ... or
Tuple tuple = nTuple( "1", "My tuple" ) ;

// ... or, Book Ntuple with a literal ID
Tuple tuple = nTuple( "mytuple", "My tuple" ) ;

// ... or, Book Ntuple with a literal ID in a sub-dir
Tuple tuple = nTuple( "subdir/mytuple", "My tuple" ) ;

// Fill and write NTuple
tuple->column( "A" , sin(0.1) );
tuple->column( "B" , cos(0.1) );
tuple->column( "C" , tan(0.1) );
tuple->write();

Attention

If the N-Tuple with given ID is already booked through automatic assignment of N-Tuple ID, the error will not be detected. Therefore it is recommended to use a non-trivial N-Tuple ID offset (property "NTupleOffSet") if one need to combine these techniques together It is still desirable to use the unique N-Tuple title to avoid a bad interference.

Parameters

ID	The forced N-Tuple ID
title	Unique title for N-Tuple
clid	N-Tuple class identifier (row or column wise)

Returns

ntuple The ntuple object
