class Decoder::THaCodaFile: public Decoder::THaCodaData


  THaCodaFile
  File of CODA data

  CODA data file, and facilities to open, close, read,
  write, filter CODA data to disk files, etc.

  This is largely a wrapper around the JLAB EVIO library.

Function documentation

THaCodaFile()

 Default constructor. Do nothing (must open file separately).

THaCodaFile(const char* filename, const char* rw = "r")

 Standard constructor

~THaCodaFile()

Destructor

Int_t codaOpen(const char* filename, Int_t mode = 1)

Int_t codaOpen(const char* filename, const char* rw, Int_t mode = 1)

Int_t codaClose()

 Close the file. Do nothing if file not opened.

Int_t codaRead()

 codaRead: Reads data from file, stored in evbuffer.
 Must be called once per event.

Int_t codaWrite(const UInt_t* evbuffer)

 codaWrite: Writes data from 'evbuf' to file

bool isOpen() const

Int_t filterToFile(const char* output_file)

 A call to filterToFile filters from present file to output_file
 using filter criteria defined by evtypes, evlist, and max_to_filt
 which are loaded by public methods of this class.  If no conditions
 were loaded, it makes a copy of the input file (i.e. no filtering).

void addEvTypeFilt(Int_t evtype_to_filt)

 Function to set up filtering by event type

void addEvListFilt(Int_t event_to_filt)

 Function to set up filtering by list of event numbers

void setMaxEvFilt(Int_t max_event)

 Function to set up the max number of events to filter

void staterr(const char* tried_to, Int_t status)

 staterr gives the non-expert user a reasonable clue
 of what the status returns from evio mean.
 Note: severe errors can cause job to exit(0)
 and the user has to pay attention to why.

void init(const char* fname = "")

void initFilter()

THaCodaFile()

THaCodaFile& operator=(const Decoder::THaCodaFile& fn)
