THcScalerEvtHandler Class Reference

Event handler for Hall C scalers.

This class does the following

For a particular set of event types (here, event type 0) decode the scalers and put some variables into global variables. The global variables can then appear in the Podd output tree T. In addition, a tree "TS" is created by this class; it contains just the scaler data by itself. Note, the "fName" is concatenated with "TS" to ensure the tree is unqiue; further, "fName" is concatenated with the name of the global variables, for uniqueness. The list of global variables and how they are tied to the scaler module and channels is defined here; eventually this will be modified to use a scaler.map file

NOTE: if you don't have the scaler map file (e.g. Leftscalevt.map) there will be no variable output to the Trees.

To use in the analyzer, your setup script needs something like this

gHaEvtHandlers->Add (new THcScalerEvtHandler("HMS","HC scaler event type 0"));

To enable debugging you may try this in the setup script

THcScalerEvtHandler *hscaler = new THcScalerEvtHandler("HS","HC scaler event type 0");
hscaler->SetDebugFile("HScaler.txt");
gHaEvtHandlers->Add (hscaler);

void THcScalerEvtHandler::SetDelayedType ( int  evtype )

virtual

Delay analysis of this event type to end.

Final scaler events generated in readout list end routines may not come in order in the data stream. If the event type of a end routine scaler event is set, then the event contents will be saved and analyzed at the end of the analysis so that time ordering of scaler events is preserved.
