bool FltCurve::build_record | ( | FltRecordWriter & | writer | ) | const [protected, virtual] |
Fills up the current record on the FltRecordWriter with data for this record, but does not advance the writer.
Returns true on success, false if there is some error.

bool FltCurve::extract_record | ( | FltRecordReader & | reader | ) | [protected, virtual] |
Fills in the information in this bead based on the information given in the indicated datagram, whose opcode has already been read.
Returns true on success, false if the datagram is invalid.

static void FltCurve::init_type | ( | ) | [inline, static] |
This function is declared non-inline to work around a compiler bug in g++ 2.96.
Making it inline seems to cause problems in the optimizer.
