Detailed Description

This class describes the T.120 logical channel.


Constructor & Destructor Documentation

H323_T120Capability::H323_T120Capability (  ) 

Create capability.


Member Function Documentation

virtual PObject* H323_T120Capability::Clone (  )  const [virtual]

Create a copy of the object.

virtual H323Channel* H323_T120Capability::CreateChannel ( H323Connection &  connection,
H323Channel::Directions  dir,
unsigned  sessionID,
const H245_H2250LogicalChannelParameters param 
) const [virtual]

Create the channel instance, allocating resources as required.

Parameters:
connection Owner connection for channel
dir Direction of channel
sessionID Session ID for RTP channel
param Parameters for channel
PBoolean H323_T120Capability::GetDynamicPortCapability (  )  const [inline]

Get the dynamic port capability. Indicates endpoint can use something other than port 1503.

References dynamicPortCapability.

virtual PString H323_T120Capability::GetFormatName (  )  const [virtual]

Get the name of the media data format this class represents.

virtual unsigned H323_T120Capability::GetSubType (  )  const [virtual]

Get the sub-type of the capability. This is a code dependent on the main type of the capability.

This returns the e_t120 enum value from the protocol ASN H245_DataApplicationCapability_application class.

virtual PBoolean H323_T120Capability::OnReceivedPDU ( const H245_DataApplicationCapability pdu  )  [virtual]

This function is called whenever and incoming TerminalCapabilitySet or OpenLogicalChannel PDU has been used to construct the control channel. It allows the capability to set from the PDU fields, information in members specific to the class.

The default behaviour gets the data rate field from the PDU.

Parameters:
pdu PDU to set information on
virtual PBoolean H323_T120Capability::OnSendingPDU ( H245_DataProtocolCapability pdu  )  const [virtual]

This function is called whenever and outgoing PDU is being constructed for the control channel. It allows the capability to set the PDU fields from information in members specific to the class.

The default behaviour sets separate LAN stack.

Parameters:
pdu PDU to set information on
virtual PBoolean H323_T120Capability::OnSendingPDU ( H245_DataMode pdu  )  const [virtual]

This function is called whenever and outgoing RequestMode PDU is being constructed for the control channel. It allows the capability to set the PDU fields from information in members specific to the class.

The default behaviour sets the pdu and calls OnSendingPDU with a H245_DataProtocolCapability parameter.

Parameters:
pdu PDU to set information on
virtual PBoolean H323_T120Capability::OnSendingPDU ( H245_DataApplicationCapability pdu  )  const [virtual]

This function is called whenever and outgoing TerminalCapabilitySet or OpenLogicalChannel PDU is being constructed for the control channel. It allows the capability to set the PDU fields from information in members specific to the class.

The default behaviour sets the pdu and calls OnSendingPDU with a H245_DataProtocolCapability parameter.

void H323_T120Capability::SetDynamicPortCapability ( PBoolean  dynamic  )  [inline]

Set the dynamic port capability. Indicates endpoint can use something other than port 1503.
