convenience method to get a histogram but checks first whether the corresponding MonitorElement is non-null.

Returns
null if the MonitorElement is null

std::string EmDQMPostProcessor::dataSet_
private

dataset with which these histograms were produced. This is set by a user parameter in the configuration file.

It is just used for writing it to the DQM output file. Useful to remember with which dataset a histogram file was produced. This code does not do much with this information (apart from copying it to the output file) but it can be used when generating reports.

bool EmDQMPostProcessor::noPhiPlots
private

read from the configuration: if set to true, efficiencies are calculated with respect to reconstructed objects (instead of generated objects). This is e.g. a useful option when running on data.
