DtPdu is the base class for all PDU's in VR-Link.
| virtual DtPdu::~DtPdu | ( | ) | [virtual] |
Destructor.
| DtPdu::DtPdu | ( | const DtPdu & | pdu, |
| DtBufferPtr | buffer = DtUSE_INTERNAL_BUFFER |
||
| ) |
Copy constructor.
| DtPdu::DtPdu | ( | ) | [protected] |
Constructor.
PDU is not fully constructed until initPdu is called.
| virtual void DtPdu::clearData | ( | ) | [protected, virtual] |
zeros out all bytes after the PDU header.
| int DtPdu::exerciseId | ( | ) | const [inline, virtual] |
References DtNetPduHeader::DtExercise, and netHeader().
| virtual DtTime DtPdu::guessTimeValid | ( | DtTime | referenceTime | ) | const [virtual] |
Since timestamp only represents number of seconds past the hour, guessTimeValid chooses the hour that would make the timestamp closest to reference time, and returns a time that is timestamp seconds past that hour.
| virtual void DtPdu::initHeader | ( | DtPduKind | kind, |
| int | size | ||
| ) | [protected, virtual] |
Initializes PDU header. Called by initPdu.
| virtual void DtPdu::initPdu | ( | int | size, |
| DtBufferPtr | buffer | ||
| ) | [protected, virtual] |
Must be called after default ctor before PDU is completely constructed.
Fills in PDU header, and initializes DtBaseMsg.
| virtual void DtPdu::initPdu | ( | const void * | initial, |
| DtBufferPtr | buffer | ||
| ) | [protected, virtual] |
Called by from-net-rep ctor. Initializes DtBaseMsg.
| virtual DtPduKind DtPdu::internalGetPduKind | ( | ) | const [protected, pure virtual] |
Returns the PDU kind associated with the derived PDU class.
Implemented in DtGriddedDataPdu, and DtEnvironmentalProcessPdu.
| DtPduKind DtPdu::kind | ( | ) | const [inline, virtual] |
Returns PDU kind from PDU header.
References netHeader().
| virtual DtProtocolFamily DtPdu::kindToFamily | ( | DtPduKind | kind | ) | const [protected, virtual] |
Maps PDU kind to ProtocolFamily.
| DtNetPduHeader * DtPdu::netHeader | ( | ) | const [inline, virtual] |
Returns a pointer to the PDU's header.
References DtBaseMsg::netRep().
Referenced by exerciseId(), kind(), protocolFamily(), protocolVersion(), setExerciseId(), setTimeStamp(), setVersion(), timeStamp(), and timeStampType().
| void * DtPdu::packet | ( | ) | const [inline, virtual] |
Older function that returns a pointer to the network representation.
The newer DtBaseMsg::netRep should generally be used instead.
References DtBaseMsg::netRep().
| virtual void DtPdu::print | ( | ) | const [virtual] |
Print the contents of the PDU by calling printToStream(DtInfo).
| virtual void DtPdu::printData | ( | ) | const [virtual] |
Print the PDU's data (not including header).
Base DtPdu version just prints hex. Use the printDataToString to put the data into a DtString instead of simply sending the output to stdout. printData() calls printDataToStream(DtInfo).
Reimplemented in DtGriddedDataPdu, and DtEnvironmentalProcessPdu.
| virtual void DtPdu::printDataToStream | ( | std::ostream & | stream | ) | const [virtual] |
Reimplemented in DtGriddedDataPdu, and DtEnvironmentalProcessPdu.

Print the PDU's header to a stream.
| virtual void DtPdu::printToStream | ( | std::ostream & | stream | ) | const [virtual] |
Print the contents of the PDU by calling printHeaderToStream and printDataToStream.
| DtProtocolFamily DtPdu::protocolFamily | ( | ) | const [inline, virtual] |
Returns protocol family from PDU header.

| void DtPdu::setStatus | ( | int | okStatus | ) | [inline, protected, virtual] |
Sets the PDU's status to okStatus.
References myOKStatus.
| void DtPdu::setTimeStamp | ( | DtTime | time, |
| DtTimeStampType | type = DtTimeStampRelative |
||
| ) | [inline, virtual] |
Set the PDU header's time stamp to reflect time and type.
Time is in seconds, but only the time modulo an hour actually gets into the time stamp.
References DtNetPduHeader::DtTime, and netHeader().
| void DtPdu::setVersion | ( | int | vers | ) | [inline, virtual] |
Set/Get protocol version from PDU header.
References netHeader(), and DtNetPduHeader::version.
| virtual void DtPdu::sizeChanged | ( | int | size | ) | [protected, virtual] |
Called by changeSize. Sets the size in the header to size.
Implements DtBaseMsg.
| int DtPdu::status | ( | ) | const [inline, virtual] |
Get PDU status.
DtSTATUS_OK means it's good. Other values indicate a bad PDU. Return codes are derived PDU-dependent.

| DtTime DtPdu::timeStamp | ( | ) | const [inline, virtual] |
Return the time (in seconds past an hour) encoded in the PDU header's time stamp.
