		Int_t	timeFromRef,
		const std::vector< int > &	timeResolutions,
		const std::map< int, int > &	busPatches
	)

Insure the histograms in hc are big enough to accomodate timeFromRef timeFromRef can be negative or positive Return 1 if a re-allocation has been performed, 0 otherwise

void FillBusPatchesMap

(

std::map< int, int > &

buspatches

)

Fill the map of buspatches, giving the relation between the bus patch id and the number of pads readout by this bus patch.

In principle (for maximum flexibility) that information should come from the configuration file. But the mapping of the detector is not a thing that is changing often, if ever, so we provide a very sensible default here.

Ain't pretty, but the code below can be cut and paste from the execution of the MakeConfigCodeForBPEVOda function in $ALICE_ROOT/../src/MUON/DA/MCHBPEVOdaUtils.C macro

Main method.

We sort the time resolutions so the finer one will be used in AssertHistogramsRange

Loop over all bus patches and compute their occupancy in the last nevents

const char* OUTPUT_FILE = "mchbpevo.root"

MUON TRACKER DA to compute the evolution of the bus patches hit count, which can be used to alert in case of high occupancy

In the end, this DA produces a Root file containing histograms with the hit count all the buspatches (that were seen in the data flow) of MCH as a function of time (and the number of events seen, so we can later on compute the occupancy)

The time resolutions used are defined in the detDB configuration file mchbpevo.conf if it exists or otherwise defaults to 60s

Note that, to avoid having to access the mapping (from the OCDB) of MCH, we do rely on some mapping information (list of bus patch ids and their number of pads) to be present in the configuration file for this DA. We also provide defaults in this code in case the configuration is not properly setup.
