#include <remote.h>
An enum to describe incoming frame. The incoming frame may be on time (perfect sequence numbers) repeated (we have already seen it before) or out of order (a frame is skipped).
enum IAX2SequenceNumbers::sequenceDefines [protected] |
| IAX2SequenceNumbers::IAX2SequenceNumbers | ( | ) | [inline] |
Constructor, which sets the in and out sequence numbers to zero
| virtual IAX2SequenceNumbers::~IAX2SequenceNumbers | ( | ) | [inline, virtual] |
Destructor, which is provided as this class contains virtual methods
| void IAX2SequenceNumbers::ZeroAllValues | ( | ) |
Initialise to Zero values
| PINDEX IAX2SequenceNumbers::InSeqNo | ( | ) |
Read the incoming sequence number
| PINDEX IAX2SequenceNumbers::OutSeqNo | ( | ) |
Read the outgoing sequence number
| PBoolean IAX2SequenceNumbers::IsSequenceNosZero | ( | ) |
Report true if the frame has inSeqNo and outSeqNo of zero, indicating if it is a "New" packet.
| void IAX2SequenceNumbers::SetInSeqNo | ( | PINDEX | newVal | ) |
Assign new value to the in (or expected) seq number
| void IAX2SequenceNumbers::SetOutSeqNo | ( | PINDEX | newVal | ) |
Assign a new value to the sequence number used for outgoing frames
| void IAX2SequenceNumbers::SetInOutSeqNo | ( | PINDEX | inVal, | |
| PINDEX | outVal | |||
| ) |
Assign a new value to the seq.in and seq.out, which is used prior to sending a frame
| void IAX2SequenceNumbers::SetAckSequenceInfo | ( | IAX2SequenceNumbers & | other | ) |
Assign the sequence nos as appropropriate for when we are sending a sequence set in a ack frame
| PBoolean IAX2SequenceNumbers::operator!= | ( | IAX2SequenceNumbers & | other | ) |
Comparison operator - tests if sequence numbers are different
| PBoolean IAX2SequenceNumbers::operator== | ( | IAX2SequenceNumbers & | other | ) |
Comparison operator - tests if sequence numbers are equal
| void IAX2SequenceNumbers::MassageSequenceForSending | ( | IAX2FullFrame & | src | ) |
Increment this sequences outSeqNo, and assign the results to the source arg
| void IAX2SequenceNumbers::WrapAroundFrameSequence | ( | IAX2SequenceNumbers & | src | ) |
Take the incoming frame, and increment seq nos by some multiple of 256 to bring them into line with the current values. Use the wrapAound member variable to do this.
| IncomingOrder IAX2SequenceNumbers::IncomingMessageInOrder | ( | IAX2FullFrame & | src | ) |
We have received a message from the remote node. Check sequence numbers are ok. reply with the appropriate enum to describe if the incoming frame is early, late, or on time
| void IAX2SequenceNumbers::CopyContents | ( | IAX2SequenceNumbers & | src | ) |
Copy the sequence info from the source argument to this class
| PString IAX2SequenceNumbers::AsString | ( | ) | const |
Report the contents as a string
| virtual void IAX2SequenceNumbers::PrintOn | ( | ostream & | strm | ) | const [virtual] |
Pretty print in and out sequence numbers to the designated stream
| PBoolean IAX2SequenceNumbers::IsFirstReply | ( | ) | [inline] |
Report PTrue if this sequnece info is the very first packet received from a remote node, where we have initiated the call
| void IAX2SequenceNumbers::AddWrapAroundValue | ( | PINDEX | newOffset | ) |
Add an offset to the inSeqNo and outSeqNo variables
PINDEX IAX2SequenceNumbers::inSeqNo [protected] |
Packet number (next incoming expected)
PINDEX IAX2SequenceNumbers::outSeqNo [protected] |
Packet number (outgoing)
PMutex IAX2SequenceNumbers::mutex [protected] |
Mutex to protect access to this structrue while doing seqno changes
PINDEX IAX2SequenceNumbers::lastSentTimeStamp [protected] |
Last sent time stamp - ensure 3 ms gap between time stamps.
IAX2PacketIdList IAX2SequenceNumbers::receivedLog [protected] |
Dictionary of timestamp and OutSeqNo for frames received by this iax device
