| virtual PBoolean H323_T38Channel::OnSendingPDU | ( | H245_OpenLogicalChannel & | openPDU | ) | const [virtual] |
Fill out the OpenLogicalChannel PDU for the particular channel type.
| openPDU | Open PDU to send. |
Reimplemented from H323DataChannel.
| virtual PBoolean H323_T38Channel::OnReceivedPDU | ( | const H245_OpenLogicalChannel & | pdu, | |
| unsigned & | errorCode | |||
| ) | [virtual] |
This is called after a request to create a channel occurs from the local machine via the H245LogicalChannelDict::Open() function, and the request has been acknowledged by the remote endpoint.
The default makes sure the parameters are compatible and passes on the PDU to the rtp session.
| pdu | Open PDU |
| errorCode | Error code on failure |
Reimplemented from H323DataChannel.
| virtual void H323_T38Channel::Close | ( | ) | [virtual] |
This is called to clean up any threads on connection termination.
Reimplemented from H323DataChannel.
| virtual void H323_T38Channel::Receive | ( | ) | [virtual] |
Handle channel data reception.
This is called by the thread started by the Start() function and is a loop reading from the transport and calling HandlePacket() for each PDU read.
| virtual void H323_T38Channel::Transmit | ( | ) | [virtual] |
Handle channel data transmission.
This is called by the thread started by the Start() function and is typically a loop reading from the codec and writing to the transport (eg an RTP_session).
| virtual PBoolean H323_T38Channel::CreateListener | ( | ) | [virtual] |
Create the H323Listener class to be used. This is called on receipt of an OpenLogicalChannel request.
The default behaviour creates a compatible listener using the connections control channel as a basis and returns PTrue if successful.
Reimplemented from H323DataChannel.
| virtual PBoolean H323_T38Channel::CreateTransport | ( | ) | [virtual] |
Create the H323Transport class to be used. This is called on receipt of an OpenLogicalChannelAck response. It should not return PTrue unless the transport member variable is set.
The default behaviour uses the connection signalling channel to create the transport and returns PTrue if successful.
Reimplemented from H323DataChannel.
