Member Function Documentation

Comparison H323_T38Capability::Compare ( const PObject &  obj  )  const

Compare two capability instances. This compares the main and sub-types of the capability.

Reimplemented from H323Capability.

virtual PObject* H323_T38Capability::Clone (  )  const [virtual]

Create a copy of the object.

virtual unsigned H323_T38Capability::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_t38fax enum value from the protocol ASN H245_DataApplicationCapability_application class.

Implements H323Capability.

virtual PString H323_T38Capability::GetFormatName (  )  const [virtual]

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

Implements H323Capability.

virtual H323Channel* H323_T38Capability::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

Implements H323Capability.

virtual BOOL H323_T38Capability::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.

Reimplemented from H323DataCapability.

virtual BOOL H323_T38Capability::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

Implements H323DataCapability.

virtual BOOL H323_T38Capability::OnSendingPDU ( H245_DataProtocolCapability proto,
H245_T38FaxProfile profile 
) 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 tcp or udp as required.

Parameters:
proto  PDU to set information on
profile  PDU to set information on

virtual BOOL H323_T38Capability::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

Reimplemented from H323DataCapability.

TransportMode H323_T38Capability::GetTransportMode (  )  const [inline]
