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.

Constructor & Destructor Documentation

H323NonStandardCapabilityInfo::H323NonStandardCapabilityInfo ( const H323EndPoint & endpoint,

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:

endpoint Endpoint to get 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

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

Member Function Documentation

PObject::Comparison H323NonStandardCapabilityInfo::CompareData ( const PBYTEArray & data ) const [protected]

Parameters:

data Data field in PDU received

PObject::Comparison H323NonStandardCapabilityInfo::CompareInfo ( const H323NonStandardCapabilityInfo & obj ) const [protected]

PObject::Comparison H323NonStandardCapabilityInfo::CompareParam ( const H245_NonStandardParameter & param ) const

BOOL H323NonStandardCapabilityInfo::OnReceivedNonStandardPDU ( const PASN_Choice & pdu,

unsigned nonStandardTag

) [protected]

virtual BOOL 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

BOOL H323NonStandardCapabilityInfo::OnSendingNonStandardPDU ( PASN_Choice & pdu,

unsigned nonStandardTag

) const [protected]

virtual BOOL 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
