FltOpcode get_opcode() const
Returns the opcode associated with the current record.
const Datagram & get_datagram()
Returns the datagram representing the entire record, less the four-byte header.
This class writes a sequence of FltRecords to an ostream, handling opcode and size counts properly.
void set_datagram(const Datagram &datagram)
Sets the datagram that will be written when advance() is called.
void set_opcode(FltOpcode opcode)
Sets the opcode associated with the current record.
The base class for all kinds of records in a MultiGen OpenFlight file.
Definition: fltRecord.h:36
virtual void output(std::ostream &out) const
Writes a quick one-line description of the bead, but not its children.
TypeHandle is the identifier used to differentiate C++ class types.
