Detailed Description

A collection of profile histograms that have the same axis.

A SFSetOfH2F contains a set of TH2F histograms; these histograms are (normally) all created by the constructor. The histograms share the same axis binning, and their names and titles are created using a BinningFun object that at the same time defines the number of histograms.

The histogram names will a concatenation of the name given by the user, and the bin name given by the BinningFun. The same applies to the title.

A SFSetOfH2F is a convenient tool to create a large set of histograms at the same time.

Functions exist to add, multiply, and divide sets of histograms. These operations are performed on pairs of corresponding histograms, if possible.

Member Function Documentation

void SFSetOfH2F::Fill (   )  [virtual]
 

The Self-filler method.

Fill() evaluates the cut object to see whether an event fulfills the cut defined by the cut object, then evaluates the BinningFun object to see into which histogram to make an entry, then evaluates the xfun object to get the abscissa and the wfun object to obtain the weight. Optionally, the iter object serves as iterator.

Implements SFO.
