Member Function Documentation

virtual PObject* H323_T120Capability::Clone

(

)

const [virtual]

Create a copy of the object.

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.

Implements H323Capability.

virtual PString H323_T120Capability::GetFormatName

(

)

const [virtual]

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

Implements H323Capability.

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

Implements H323Capability.

virtual BOOL 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.

Reimplemented from H323DataCapability.

virtual BOOL 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

Implements H323DataCapability.

virtual BOOL 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 BOOL 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

Reimplemented from H323DataCapability.

BOOL H323_T120Capability::GetDynamicPortCapability

(

)

const [inline]

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

void H323_T120Capability::SetDynamicPortCapability

(

BOOL

dynamic

)

[inline]

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