A class to retrieve the individual data elements previously stored in a Datagram.
This is a base class for both FltFace and FltMesh, which are two different kinds of geometric primiti...
Definition: fltGeometry.h:33
This is the first bead in the file, the top of the bead hierarchy, and the primary interface to readi...
Definition: fltHeader.h:44
This class turns an istream into a sequence of FltRecords by reading a sequence of Datagrams and extr...
FltOpcode get_opcode() const
Returns the opcode associated with the current record.
DatagramIterator & get_iterator()
Returns an iterator suitable for extracting data from the current record.
This class writes a sequence of FltRecords to an ostream, handling opcode and size counts properly.
void set_opcode(FltOpcode opcode)
Sets the opcode associated with the current record.
void check_remaining_size(const DatagramIterator &di, const std::string &name=std::string()) const
Checks that the iterator has no bytes left, as it should at the end of a successfully read record.
