This class describes a unidirectional logical channel between the two endpoints. They may be created and deleted as required in the H245 protocol.
An application may create a descendent off this class and override functions as required for operating the channel protocol.

H323UnidirectionalChannel::~H323UnidirectionalChannel | ( | ) |
Destroy the channel, deleting the associated media stream.
|
virtual |
Indicate the direction of the channel. Return if the channel is bidirectional, or unidirectional, and which direction for th latter case.
Implements H323Channel.
|
virtual |
Get the media stream associated with this logical channel. The default behaviour returns NULL.
Reimplemented from H323Channel.
|
protectedvirtual |
Reimplemented from H323Channel.
Reimplemented in H323DataChannel.
|
virtual |
Open the channel.
Reimplemented from H323Channel.
|
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 |
This is called when the channel can start transferring data. The default action is to start one threads, with it either calling Receive() or Transmit() depending on the receiver member variable.
Implements H323Channel.
Reimplemented in H323_ExternalRTPChannel.
