~UDPTLSession

(

)

Destructor

UDPTLSession	(	u_int16_t	maxLen = 250,
		u_int8_t	maxSec = 2
	)		[protected]

UDPTL Session constructor

Parameters:

maxLen	Maximum length of UDPTL packet, at least longest primary IFP + 5 bytes
maxSec	Maximum number of secondary IFPs, set to zero to disable

Member Function Documentation

virtual RTPTransport* createTransport

(

)

[protected, virtual]

Create a new UDPTL transport for this session. Override this method to create objects derived from RTPTransport.

Returns:

Pointer to the new transport or NULL on failure

Reimplemented from UDPSession.

bool localAddr

(

SocketAddr &

addr

)

[inline]

Set the local network address of the RTP transport of this session

Parameters:

addr	New local RTP transport address

Returns:

True if address set, false if a failure occured

u_int16_t maxLen

(

)

const [inline]

Get the maximum UDPTL packet length

Returns:

Maximum length of UDPTL packet length in bytes

u_int8_t maxSec

(

)

const [inline]

Get the maximum number of UDPTL secondary IFPs

Returns:

Maximum number of secondary IFPs, zero if disabled

virtual void rtpData	(	const void *	data,
		int	len
	)		[virtual]

This method is called to send or process an UDPTL packet

Parameters:

data	Pointer to raw UDPTL data
len	Length of the data packet

Reimplemented from RTPProcessor.

virtual void timerTick

(

const Time &

when

)

[protected, virtual]

Method called periodically to push any asynchronous data or statistics

Parameters:

when	Time to use as base in all computing

Implements RTPProcessor.

virtual void udptlRecv	(	const void *	data,
		int	len,
		u_int16_t	seq,
		bool	recovered
	)		[protected, pure virtual]

Method called when UDPTL data is received

Parameters:

data	Pointer to IFP block
len	Length of the IFP block
seq	Sequence number of the block
recovered	True if the IFP block was recovered after data loss

bool udptlSend	(	const void *	data,
		int	len,
		u_int16_t	seq
	)

Send UDPTL data over the transport, add older blocks for error recovery

Parameters:

data	Pointer to IFP block to send as primary
len	Length of primary IFP block
seq	Sequence number to incorporate in message

Returns:

True if data block was sent, false if an error occured
