class Decoder::THaCodaDecoder: public THaEvData

   Hall A Event Data from one CODA "Event"

   THaCodaDecoder contains facilities to load an event buffer
   from a CODA "event" and get information about the event,
   such as event type, TDC hits, scalers, prescale factors,
   etc.  The idea of an "event" is not just a physics trigger,
   but more generally any separate record inserted into CODA,
   e.g. EPICS insertion.  The user must "LoadEvent" each
   event before extracting information about the event.
   The "evbuffer" may come from a CODA file or ET connection.
   There is no need to create/destroy an THaEvData object each
   event because hit counters are cleared each event.
   There are various kinds of events including:
      1. physics triggers
      2. scaler events (asynch insertion of scalers)
      3. EPICS "events"
      4. prescale factors (one "event" at start of run).
      5. etc, etc. (see the online DAQ documentation)
   Public routines allow to fetch these data.

Int_t GetPrescaleFactor(Int_t trigger) const
 To get the prescale factors for trigger number "trigger_type"
 (valid types are 1,2,3...)
Int_t LoadEvent(const UInt_t* evbuffer)
 Public interface to decode the event.  Note, LoadEvent()
 MUST be called once per event BEFORE you can extract
 information about the event.
Int_t gendecode(const UInt_t* evbuffer)
 Main engine for decoding, called by public LoadEvent() methods
void dump(const UInt_t* evbuffer)
Int_t physics_decode(const UInt_t* evbuffer)
Int_t epics_decode(const UInt_t* evbuffer)
Int_t prescale_decode(const UInt_t* evbuffer)
 Decodes prescale factors from either
 TS_PRESCALE_EVTYPE(default) = PS factors
 read from Trig. Super. registors (since 11/03)
   - or -
 PRESCALE_EVTYPE = PS factors from traditional
     "prescale.dat" file.
Int_t scaler_event_decode(const UInt_t* evbuffer)
 Decode scalers
Int_t GetScaler(const TString& spec, Int_t slot, Int_t chan) const
 Get scaler data by spectrometer, slot, and channel
 spec = "left" or "right" for the "scaler events" (type 140)
 and spec = "evleft" and "evright" for scalers
 that are part of the event (ev) readout.
Int_t GetScaler(Int_t roc, Int_t slot, Int_t chan) const
 Get scaler data by roc, slot, chan.
Bool_t IsLoadedEpics(const char* tag) const
 Test if the given EPICS variable name has been loaded
double GetEpicsData(const char* tag, Int_t event = 0) const
 EPICS data which is nearest CODA event# 'event'
 event == 0 --> get latest data
 Tag is EPICS variable, e.g. 'IPM1H04B.XPOS'
TString GetEpicsString(const char* tag, Int_t event = 0) const
 EPICS string data which is nearest CODA event# 'event'
 event == 0 --> get latest data
double GetEpicsTime(const char* tag, Int_t event = 0) const
 EPICS time stamp
 event == 0 --> get latest data

 Decode VME
Int_t camac_decode(Int_t roc, const UInt_t* evbuffer, Int_t p1, Int_t p2)
Int_t loadFlag(const UInt_t* evbuffer)
 Looks for buffer mode and synch problems.  The latter are recoverable
 but extremely rare, so I haven't bothered to write recovery a code yet,
 but at least this warns you.
void SetRunTime(ULong64_t tloc)
 Set run time and re-initialize crate map (and possibly other
 database parameters for the new time.
void PrintOut() const
{ dump(buffer); }
