class Decoder::THaUsrstrutils


 R. Michaels, March 2000
 Updated string_from_buffer, May 2007
 THaUsrstrutils = USeR STRing UTILitieS.
 The code below is what is used by DAQ to interpret strings
 like prescale factors
 Yes, this is mostly old-style C, but it
 has the advantage that the interpretation should
 be identical to what the DAQ used.

Function documentation

int getflag(const char* s) const

char* getstr(const char* s) const

unsigned int getint(const char* s) const

void getflagpos_instring(const char* constr, const char* s, const char** pos_ret, const char** val_ret)

void string_from_evbuffer(const UInt_t* evbuffer, int nlen = MAX)

 Routine string_from_evbuffer loads the configstr from the event buffer.
 It has the same strengths and weaknesses as the DAQ code,
 hence the interpretation should be the same.

 nlen is the length of the string data (from CODA) in longwords (4 bytes)

 R. Michaels, updated to make the algorithm closely resemble the
              usrstrutils.c used by trigger supervisor.
