| H323_H224Channel::~H323_H224Channel | ( | ) |
| virtual H323Channel::Directions H323_H224Channel::GetDirection | ( | ) | const [virtual] |
Indicate the direction of the channel. Return if the channel is bidirectional, or unidirectional, and which direction for the latter case.
Implements H323Channel.
| virtual BOOL H323_H224Channel::SetInitialBandwidth | ( | ) | [virtual] |
Set the initial bandwidth for the channel. This calculates the initial bandwidth required by the channel and returns TRUE if the connection can support this bandwidth.
The default behaviour gets the bandwidth requirement from the codec object created by the channel.
Implements H323Channel.
| virtual BOOL H323_H224Channel::Open | ( | ) | [virtual] |
Open the channel. The default behaviour just calls connection.OnStartLogicalChannel() and if successful sets the opened member variable.
Reimplemented from H323Channel.
| virtual BOOL H323_H224Channel::Start | ( | ) | [virtual] |
This is called when the channel can start transferring data.
Implements H323Channel.
| virtual void H323_H224Channel::Close | ( | ) | [virtual] |
This is called to clean up any threads on connection termination.
Reimplemented from H323Channel.
| virtual BOOL H323_H224Channel::OnSendingPDU | ( | H245_OpenLogicalChannel & | openPDU | ) | const [virtual] |
Fill out the OpenLogicalChannel PDU for the particular channel type.
Implements H323Channel.
| virtual void H323_H224Channel::OnSendOpenAck | ( | const H245_OpenLogicalChannel & | openPDU, | |
| H245_OpenLogicalChannelAck & | ack | |||
| ) | const [virtual] |
This is called when request to create a channel is received from a remote machine and is about to be acknowledged.
The default behaviour does nothing.
Reimplemented from H323Channel.
| virtual BOOL H323_H224Channel::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 behaviour just returns TRUE.
Reimplemented from H323Channel.
| virtual BOOL H323_H224Channel::OnReceivedAckPDU | ( | const H245_OpenLogicalChannelAck & | pdu | ) | [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 behaviour just returns TRUE.
Reimplemented from H323Channel.
| virtual BOOL H323_H224Channel::OnSendingPDU | ( | H245_H2250LogicalChannelParameters & | param | ) | const [virtual] |
| virtual void H323_H224Channel::OnSendOpenAck | ( | H245_H2250LogicalChannelAckParameters & | param | ) | const [virtual] |
| virtual BOOL H323_H224Channel::OnReceivedPDU | ( | const H245_H2250LogicalChannelParameters & | param, | |
| unsigned & | errorCode | |||
| ) | [virtual] |
| virtual BOOL H323_H224Channel::OnReceivedAckPDU | ( | const H245_H2250LogicalChannelAckParameters & | param | ) | [virtual] |
| virtual BOOL H323_H224Channel::SetDynamicRTPPayloadType | ( | int | newType | ) | [virtual] |
| RTP_DataFrame::PayloadTypes H323_H224Channel::GetDynamicRTPPayloadType | ( | ) | const [inline] |
| virtual OpalMediaStream* H323_H224Channel::GetMediaStream | ( | BOOL | deleted = FALSE |
) | const [virtual] |
Get the media stream associated with this logical channel.
If the argument is set to TRUE, the mediaStream is about to be deleted so all internal references to the mediaStream must be removed.
The default behaviour returns NULL.
Implements H323Channel.
| OpalH224Handler* H323_H224Channel::GetHandler | ( | ) | const [inline] |
| virtual BOOL H323_H224Channel::ExtractTransport | ( | const H245_TransportAddress & | pdu, | |
