Detailed Description

The FMS fast simulator maker.

Populates the FMS hit collection in StEvent with StFmsHits, using Geant hits from the g2t table as input. Simulates digitisation of hit energy using gains from the database.

Member Enumeration Documentation

enum StFmsSimulatorMaker::StFmsDetectorId [private]

Enumeration for FPD and FMS subdetectors.

The numerical values are defined for compatibility with the detector ID values expected by StFmsHit i.e. the detector ID numbers defined by StFmsChannelGeometry in the database. Only subdetectors that are possible return values from getDetectorId() are included; there are other subdetectors, but they are not valid return values (hits corresponding to these subdetectors will return kFmsInvalidDetectorId).

Member Function Documentation

void StFmsSimulatorMaker::fillStEvent ( StEvent *  event) [private]

Fills the StFmsCollection of StEvent with hits from an StMcEvent.

Definition at line 49 of file StFmsSimulatorMaker.cxx.

Here is the call graph for this function:

Here is the caller graph for this function:

const char * StFmsSimulatorMaker::GetCVS ( ) const [inline, virtual]

Standard overload of StMaker::GetCVS()

Definition at line 116 of file StFmsSimulatorMaker.h.

Int_t StFmsSimulatorMaker::getDetectorId ( const g2t_emc_hit_st &  hit) const [private]

Returns the detector ID of an FPD or FMS detector subsystem.

Detector ID numbers are those used by StFmsChannelGeometry (or see StFmsDetectorID in this class). Returns kFmsInvalidDetectorId if the detector ID cannot be determined, or corresponds to an unsupported subdetector.

Definition at line 149 of file StFmsSimulatorMaker.cxx.

Here is the caller graph for this function:

Int_t StFmsSimulatorMaker::Make ( )

Populate StEvent with FMS g2t Geant hits for the current event.

Returns kStOk in case of success, kStError otherwise.

Definition at line 26 of file StFmsSimulatorMaker.cxx.

Here is the call graph for this function:

StFmsHit * StFmsSimulatorMaker::makeFmsHit ( const g2t_emc_hit_st &  hit) [private]

Constructs and returns an StFmsHit from a g2t_emc_hit_st.

The StFmsHit is allocated via new and so needs to be deleted by the user, or passed to a container that takes ownership of it.

Here is the call graph for this function:

Here is the caller graph for this function:

void StFmsSimulatorMaker::printStEventSummary ( const StEvent *  event) [private]

Prints the total number of hits and energy in each detector subsystem.
