Detailed Description

This class describes the interface to a non-standard codec used to transfer data via the logical channels opened and managed by the H323 control channel.

It is expected that an application makes a descendent off H323NonStandardAudioCapability or H323NonStandardVideoCapability which multiply inherit from this class.

Member Typedef Documentation

typedef PObject::Comparison(* H323NonStandardCapabilityInfo::CompareFuncType)(struct PluginCodec_H323NonStandardCodecData *)

Constructor & Destructor Documentation

H323NonStandardCapabilityInfo::H323NonStandardCapabilityInfo	(	CompareFuncType	compareFunc,
		const BYTE *	dataBlock,
		PINDEX	dataSize
	)

Create a new set of information about a non-standard codec.

Parameters

dataBlock	Non-Standard data for codec type
dataSize	Size of dataBlock. If 0 and dataBlock != NULL use strlen(dataBlock)

H323NonStandardCapabilityInfo::H323NonStandardCapabilityInfo	(	const BYTE *	dataBlock,
		PINDEX	dataSize,
		PINDEX	comparisonOffset = 0,
		PINDEX	comparisonLength = P_MAX_INDEX
	)

Create a new set of information about a non-standard codec.

Parameters

dataBlock	Non-Standard data for codec type
dataSize	Size of dataBlock. If 0 and dataBlock != NULL use strlen(dataBlock)
comparisonOffset	Offset into dataBlock to compare
comparisonLength	Length of bytes to compare

H323NonStandardCapabilityInfo::H323NonStandardCapabilityInfo	(	const PString &	oid,
		const BYTE *	dataBlock,
		PINDEX	dataSize,
		PINDEX	comparisonOffset = 0,
		PINDEX	comparisonLength = P_MAX_INDEX
	)

Create a new set of information about a non-standard codec.

Parameters

dataBlock	Non-Standard data for codec type
dataSize	Size of dataBlock. If 0 and dataBlock != NULL use strlen(dataBlock)

H323NonStandardCapabilityInfo::H323NonStandardCapabilityInfo	(	BYTE	country,
		BYTE	extension,
		WORD	maufacturer,
		const BYTE *	dataBlock,
		PINDEX	dataSize,
		PINDEX	comparisonOffset = 0,
		PINDEX	comparisonLength = P_MAX_INDEX
	)

Create a new set of information about a non-standard codec.

Parameters

country	t35 information
extension	t35 information
maufacturer	t35 information
dataBlock	Non-Standard data for codec type
dataSize	Size of dataBlock. If 0 and dataBlock != NULL use strlen(dataBlock)
comparisonOffset	Offset into dataBlock to compare
comparisonLength	Length of bytes to compare

virtual PBoolean H323NonStandardCapabilityInfo::OnReceivedPDU ( const PBYTEArray &  data )

virtual

This function validates and uses the non-standard data field.

The default behaviour returns true if data is equal to fixedData.

Parameters

data	Data field in PDU received

PBoolean H323NonStandardCapabilityInfo::OnSendingNonStandardPDU ( PASN_Choice &  pdu, unsigned  nonStandardTag  ) const

protected

virtual PBoolean H323NonStandardCapabilityInfo::OnSendingPDU ( PBYTEArray &  data ) const

virtual

This function gets the non-standard data field.

The default behaviour sets data to fixedData.

Parameters

data	Data field in PDU to send
