ADCTDCMerger(EventMergerConstants constants, DataEvent signal, List<DataEvent>... bgs)	ADC-TDC merger tool: merges raw hits from physics and background events, accounting for pile-ups

Method Summary

Modifier and Type	Method	Description
final List<ADCTDCMerger.DGTZ>	merge(List<ADCTDCMerger.DGTZ> signal, List<ADCTDCMerger.DGTZ> background)	Merge physics signals hit with background hits
DataBank	mergeADCs(DetectorType detector, List<Integer> layers)	Merge ADC banks for data (signal) and background events for the selected detector and layers In case of multiple hit on same detector element, only first hit in time is kept unless the double-hit suppression flag, suppressDoubleHits, is set to false
DataBank	mergeTDCs(DetectorType detector, List<Integer> layers)	Merge TDC banks for data (signal) and background events for the selected detector and layers Use two background events shifted in time to extend the time range of the backgrounds Multiple hits on the same components are kept if time distance exceed the holdoff time
List<ADCTDCMerger.DGTZ>	readADCs(DetectorType detector, DataBank bank)	Reads ADC bank and returns list of hits
List<ADCTDCMerger.DGTZ>	readTDCs(DetectorType detector, DataBank bank)	Read TDC bank and return list of hit
void	setPreserveHitOrder(boolean value)	Set flag to control the final hit list order
void	setSelectedOrders(RawBank.OrderType[] orders)	Set list or order types to save
void	setSuppressDoubleHits(boolean value)	Set pile-up operation mode: keep first hit in time if true or both if false
final DataBank	writeToBank(DataEvent event, String name, List<ADCTDCMerger.DGTZ> dgtzs)	Write list of hits to bank based on hit status
