Constructor & Destructor Documentation

OpalRTPSessionManager::OpalRTPSessionManager

(

OpalRTPConnection &

connection

)

Construct new session manager database.

Parameters:

connection

Owner connection for RTP sessions

OpalRTPSessionManager::~OpalRTPSessionManager

(

)

Destroy sessions, unlinking from connection.

OpalRTPSessionManager::OpalRTPSessionManager

(

const OpalRTPSessionManager &

other

)

Copy constructor - maintain list in OpalRTPConnection.

Member Function Documentation

void OpalRTPSessionManager::AddMediaSession	(	OpalMediaSession *	session,
		const OpalMediaType &	mediaType
	)

Parameters:

	session	Session to add.
	mediaType	initial media type for this session

void OpalRTPSessionManager::AddSession	(	RTP_Session *	session,
		const OpalMediaType &	mediaType
	)

Add an RTP session for the specified ID.

This function MUST be called only after the UseSession() function has returned NULL. The mutex flag is left locked in that case. This function expects the mutex to be locked and unlocks it automatically.

Parameters:

	session	Session to add.
	mediaType	initial media type for this session

virtual bool OpalRTPSessionManager::AllSessionsFailing

(

)

[virtual]

bool OpalRTPSessionManager::ChangeSessionID	(	unsigned	fromSessionID,
		unsigned	toSessionID
	)

Change the sessionID for an existing session. This will adjust the RTP session and media streams.

Return false if no such session exists.

Parameters:

	fromSessionID	Session ID to search for
	toSessionID	Session ID to change to

virtual RTP_UDP* OpalRTPSessionManager::FindSessionByLocalPort

(

WORD

port

)

const [virtual]

Find an RTP session for the specified local port. If there is no session, NULL is returned.

Parameters:

port

Local port number

OpalMediaSession* OpalRTPSessionManager::GetMediaSession

(

unsigned

sessionID

)

const

PMutex& OpalRTPSessionManager::GetMutex

(

)

[inline]

References m_mutex.

unsigned OpalRTPSessionManager::GetNextSessionID

(

)

Get next available session ID for the media type.

RTP_Session* OpalRTPSessionManager::GetSession

(

unsigned

sessionID

)

const

Get a session for the specified ID.

Parameters:

sessionID

Session ID to get.

void OpalRTPSessionManager::operator=

(

const OpalRTPSessionManager &

other

)

[inline]

Assignment of RTP session managers.

References sessions.

OpalRTPSessionManager::PDICTIONARY	(	SessionDict	,
		POrdinalKey	,
		OpalMediaSession
	)			[protected]

void OpalRTPSessionManager::ReleaseSession	(	unsigned	sessionID,
		PBoolean	clearAll = PFalse
	)

Release the session.

Parameters:

	sessionID	Session ID to release.
	clearAll	Clear all sessions with that ID
