class THaSlotData

   Data in one slot of one crate from DAQ.

   THaSlotData contains data from one slot of one crate
   from a CODA event.  Public methods allow to obtain
   raw data for this crate & slot, or to obtain TDC, ADC,
   or scaler data for each channel in the slot.  Methods
   clearEvent() and loadData() should only be used by
   the decoder.  WARNING: For efficiency, only the
   hit counters are zero'd each event, not the data
   arrays, see below.

Function documentation

THaSlotData(const THaSlotData& )
THaSlotData(int crate, int slot)
void define(int crate, int slot, UShort_t nchan = DEFNCHAN, UShort_t ndata = DEFNDATA, UShort_t nhitperchan = DEFNHITCHAN)
 Must call define once if you are really going to use this slot.
 Otherwise its an empty slot which does not use much memory.
int loadData(const char* type, int chan, int dat, int raw)
 loadData loads the data into storage arrays.
void print()
int getRawData(int hit) const
______________ inline functions _____________________________________________
int getRawData(int chan, int hit) const
int getNumHits(int chan) const
 Num hits on a channel
int getNumChan()
 Num unique channels # hit
int getNextChan(int index) const
 List of unique channels hit
int getData(int chan, int hit) const
const char* devType()
void clearEvent()
 Only the minimum is cleared; e.g. data array is not cleared.
 CAUTION: this code is critical for performance

int getNumRaw()

int getCrate()
