class THaEvData: public TObject

 Device type in crate, slot

 Set run time and re-initialize crate map (and possibly other
 database parameters for the new time.

 Enable/disable run time reporting

 Enable/disable helicity decoding

 Enable/disable scaler decoding

 Set verbosity level. Identical to SetDebug(). Kept for compatibility.

 Set debug level

 Hexdump buffer 'cbuff' of length 'nlen'

 Static function to set fgDefaultCrateMapName. Call this function to set a
 global default name for all decoder instances before initialization. This
 is usually what you want to do for a given replay.

 Set fCrateMapName for this decoder instance only

 Activate crate/slot

TODO

 Print the contents of (crate, slot).

 Update lists of used/clearable slots in case crate map changed

Utility function to index into the crateslot array

Like idx() const, but initializes empty slots

 Number hits in crate, slot, channel

 Return the data in crate, slot, channel #chan and hit# hit

 Number of raw words in crate, slot

 Raw words in crate, slot

 Return the Rawdata in crate, slot, channel #chan and hit# hit

 Raw words in evbuffer at location #i.

 Raw words in evbuffer within crate #crate.

 Direct access to the event buffer for the given crate,
 e.g. for fast header word searches

 To tell if the index "i" poInt_ts to a word inside crate #crate.

 Get number of unique channels hit

 Get list of unique channels hit (indexed by index=0,getNumChan()-1)

 Either 'event type 140' or events with the synchronous readout
 of scalers (roc11, etc).
 Important: A scaler event can also be a physics event.

 Test if helicity decoding enabled

 Test if scaler decoding enabled

 Load CODA data evbuffer. Derived classes MUST implement this function.

 Basic access to the decoded data

 Run time/date. Time of prestart event (UNIX time).

 Optional functionality that may be implemented by derived classes

 Returns Beam Helicity (-1,0,+1)  '0' is 'unknown'

 Beam Helicity for spec="left","right"

 User can GetScaler, alternativly to GetSlotData for scalers
 spec = "left", "right", "rcs" for event type 140 scaler "events"
 spec = "evleft" or "evright" for L,R scalers injected into datastream.
