## Detailed Description

This class describes a bidirectional 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.

## Constructor & Destructor Documentation

H323BidirectionalChannel::H323BidirectionalChannel | ( | H323Connection & | connection,
|  | const H323Capability & | capability
| ) |  |

Create a new channel.

Parameters

  connection | Connection to endpoint for channel
  capability | Capability channel is using

## Member Function Documentation

virtual Directions H323BidirectionalChannel::GetDirection | ( |  | ) | const

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 PBoolean H323BidirectionalChannel::Start | ( |  | ) |

virtual

This is called when the channel can start transferring data. The default action is to start two threads, one calls Receive() and the other calls Transmit().

Implements H323Channel.
