DtRecordSetPdu is an abstract base class used by PDUs which require the record set functionality.
| virtual DtRecordSetPdu::~DtRecordSetPdu | ( | ) | [virtual] |
destructor
| DtRecordSetPdu::DtRecordSetPdu | ( | ) | [protected] |
Constructors (protected because this is an abstract base class).
| DtRecordSetPdu::DtRecordSetPdu | ( | const DtRecordSetPdu & | orig | ) | [protected] |
| virtual bool DtRecordSetPdu::getRecordSet | ( | int | index, |
| DtRecordSet & | recSet | ||
| ) | const [virtual] |
| virtual int DtRecordSetPdu::netRecordSetLength | ( | ) | const [protected, virtual] |
Returns the length of data used by the record sets beginning at the location specified by netRecordSetPduStruct().
This can be used by the derived class if any data follows the record set data.
| virtual DtNetRecordSetPdu* DtRecordSetPdu::netRecordSetPduStruct | ( | ) | const [protected, pure virtual] |
Returns a pointer to the beginning of the record set data struct.
This must be implemented by the derived class because the location of the record sets within the PDU can vary.
Implemented in DtTransferControlRequestPdu, DtRecordPdu, and DtSetRecordPdu.
| virtual DtU32 DtRecordSetPdu::numRecordSets | ( | ) | const [virtual] |
| DtRecordSetPdu& DtRecordSetPdu::operator= | ( | const DtRecordSetPdu & | orig | ) |
Assignment operator.
| virtual void DtRecordSetPdu::printData | ( | ) | const [virtual] |
Print the data contained by this PDU.
Reimplemented from DtPdu.
Reimplemented in DtTransferControlRequestPdu, DtRecordPdu, and DtSetRecordPdu.
| virtual void DtRecordSetPdu::printDataToStream | ( | std::ostream & | stream | ) | const [virtual] |
Print the data to a stream.
Reimplemented from DtPdu.
Reimplemented in DtTransferControlRequestPdu, DtRecordPdu, and DtSetRecordPdu.
| virtual int DtRecordSetPdu::recordSetOffset | ( | int | recordSetIndex | ) | const [protected, virtual] |
Returns a buffer offset to the given record set.
| DtRecordSetPdu* DtRecordSetPdu::self | ( | ) | const [protected] |
Casts the 'this' pointer for changing elements in a const function.
Non virtual, since you can't override based on return type.
Reimplemented in DtTransferControlRequestPdu, DtRecordPdu, and DtSetRecordPdu.
| virtual bool DtRecordSetPdu::setNumRecordSets | ( | DtU32 | numSets | ) | [virtual] |
Set/Get the number of record sets.
| virtual bool DtRecordSetPdu::setRecordSet | ( | int | index, |
| const DtRecordSet & | recSet | ||
| ) | [virtual] |
Set/Get a record set.
If the index is out of bounds, then false is returned. If the space would exceed the maximum space permitted for a PDU (for a set) then false may be returned.
| bool DtRecordSetPdu::validateRecordSets | ( | DtNetRecordSetPdu & | netStruct | ) | [protected] |
This function checks the data records for consistency between the actual size of the PDU and the size suggested by the PDU.
It also tries to fix any problems that are detected. This function is intended to be called in the PDU constructor that accepts network data immediately following initpdu. Non-virtual, since meant to be called from ctor.
| virtual char* DtRecordSetPdu::var | ( | ) | const [protected, virtual] |
Returns a pointer to the first byte of variable length data.
int DtRecordSetPdu::mySaveBuffCount [protected] |
int DtRecordSetPdu::mySaveRecCount [protected] |
These are used by recordSetOffset() to save the value and index of the last offset which was computed in case it can be used again.
