virtual PString H323_H224_AnnexQCapability::GetFormatName ( ) const
virtual

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

Implements H323Capability.

virtual unsigned H323_H224_AnnexQCapability::GetSubType ( ) const
virtual

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

Implements H323Capability.

virtual PBoolean H323_H224_AnnexQCapability::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 is pure.

Reimplemented from H323DataCapability.

virtual PBoolean H323_H224_AnnexQCapability::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 is pure.

Reimplemented from H323DataCapability.

virtual PBoolean H323_H224_AnnexQCapability::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 PDUs tag according to the GetSubType() function (translated to different enum).

Implements H323DataCapability.
