Member Function Documentation

virtual PBoolean OpalListenerUDP::Open	(	const PNotifier &	acceptHandler,
		ThreadMode	mode = SpawnNewThreadMode
	)			[virtual]

Open the listener. Listen for an incoming connection and create a OpalTransport of the appropriate subclass.

If notifier function acceptHandler is non-NULL a thread is spawned to listen for incoming connections. The acceptHandler is called when a new connection is created. The INT parameter to the acceptHandler is a pointer to the new OpalTransport instance created by the listener.

If singleThread is PFalse the acceptHandler function is called in the context of a new thread and the continues to listen for more connections. If PTrue, then the acceptHandler function is called from within the listener threads context and no more connections are created. That is only a single connection is ever created by this listener.

If acceptHandler is NULL, then no thread is started and it is assumed that the caller is responsible for calling Accept() and waiting for the new connection.

Parameters:

acceptHandler	Handler function for new connections
mode	How handler function is called thread wise

Implements OpalListener.

virtual PBoolean OpalListenerUDP::IsOpen

(

)

[virtual]

Indicate if the listener is open.

Implements OpalListener.

virtual void OpalListenerUDP::Close

(

)

[virtual]

Stop the listener thread and no longer accept incoming connections.

Implements OpalListener.

virtual OpalTransport* OpalListenerUDP::Accept

(

const PTimeInterval &

timeout

)

[virtual]

Accept a new incoming transport.

Parameters:

timeout

Time to wait for incoming connection

Implements OpalListener.

virtual OpalTransport* OpalListenerUDP::CreateTransport	(	const OpalTransportAddress &	localAddress,
		const OpalTransportAddress &	remoteAddress
	)			const [virtual]

Create a transport compatible with this listener.

Implements OpalListener.

virtual OpalTransportAddress OpalListenerUDP::GetLocalAddress

(

const OpalTransportAddress &

remoteAddress = OpalTransportAddress()

)

const [virtual]

Get the local transport address on which this listener may be accessed. If remoteAddress is present and is an address that requires NAT for connectivity, then the returned address is adjusted to return the external address and port.

Reimplemented from OpalListenerIP.

virtual const char* OpalListenerUDP::GetProtoPrefix

(

)

const [protected, virtual]

Implements OpalListenerIP.
