HepTupleManager

HepTupleManager - an empty base class for different ntuple/histogram systems.

The main reason to have a HepTupleManager base class is to be able to create a new ntuple or histogram without knowing what the underlying system is (eg. hippo, hbook).

While all the methods of HepTupleManager have been implemented, all appropriate methods should be re-implemented by a subclass. The implementations are provided since a particular subclass may understand only tuples or only histograms, and therefore the methods cannot be pure virtual.

Declaration

class HepTupleManager

Public Member Functions

Constructor

HepTupleManager()

Destructor

virtual ~HepTupleManager()

clearAllData

virtual void clearAllData()

Call clearData() for all managed tuples (see HepTuple).

dumpAllData

virtual void dumpAllData()

Call dumpData() for all managed tuples (see HepTuple).

histogram

virtual HepHistogram * histogram(const char *pl_title, int nBins, float low, float high)

Create a 1D histogram. Behaves generally like ntuple().

virtual HepHistogram * histogram(const char *pl_title, int nBinsX, float lowX, float highX, int nBinsY, float lowY, float highY)

Create a 2D histogram. Behaves generally like ntuple().

ntuple

virtual HepTuple * ntuple(const char *nt_title)

This function returns a pointer to the ntuple with the given title. If the ntuple is known (ie. there is an ntuple with that title), the existing ntuple is returned. If it is not known, a new one is created.

write

virtual int write() = 0

Write the ntuples/histograms into the file. Return zero if successful, non-zero otherwise.
