Member Function Documentation

FltError FltRecordWriter::advance (   )

Writes the current record to the flt file, and resets the current record to receive new data. Returns FE_ok on success, or something else on error. Definition at line 122 of file fltRecordWriter.cxx. References _datagram, _out, FE_write_error, and flt_error_abort.

const Datagram& FltRecordWriter::get_datagram (   )  const

void FltRecordWriter::set_datagram (  const Datagram &  datagram  )

Sets the datagram that will be written when advance() is called. Definition at line 84 of file fltRecordWriter.cxx. References _datagram.

void FltRecordWriter::set_opcode (  FltOpcode  opcode  )

Sets the opcode associated with the current record. Definition at line 69 of file fltRecordWriter.cxx. References _datagram.

Datagram & FltRecordWriter::update_datagram (   )

Returns a modifiable reference to the datagram associated with the current record. This datagram should then be stuffed with data corresponding to the data in the record, in preparation for calling advance() to write the data. Definition at line 105 of file fltRecordWriter.cxx.

FltError FltRecordWriter::write_instance_def (  FltHeader *  header, int  instance_index )

Ensures that the given instance definition has already been written to the file. If it has not, writes it now. Definition at line 199 of file fltRecordWriter.cxx.

FltError FltRecordWriter::write_record (  FltOpcode  opcode, const Datagram &  datagram = Datagram() )

A convenience function to quickly write a simple record that consists of an opcode and possibly a datagram. Definition at line 180 of file fltRecordWriter.cxx.
