Clear()

IMPORT_C void

Clear

(

)

[virtual]

From CASRSHwDevice Clears Hw Device, counter part for InitializeL()

ConfigurationData(TUint32, TUint32, TUint32, TUint32)

HBufC8 *	ConfigurationData	(	TUint32	aPackageType,
			TUint32	aPackageID,
			TUint32	aStartPosition = 0,
			TUint32	aEndPosition = KMaxTUint32
		)	[private, virtual]

Function to notify that configuration data is needed. Called by CTtpCallback.

Parameters

TUint32 aPackageType	Type identifier.
TUint32 aPackageID	Package identifier.
TUint32 aStartPosition = 0	First byte.
TUint32 aEndPosition = KMaxTUint32	Last byte. If greater than the size of the data, rest of the data is given.

ConvertTextL(const TDesC &, TLanguage &)

IMPORT_C HBufC8 *	ConvertTextL	(	const TDesC &	aText,
			TLanguage &	aLanguage
		)

Use to convert text to phonemes.

Parameters

const TDesC & aText	Text to be converted
TLanguage & aLanguage	Used language

ConvertWordListL(CSITtpWordList &, const RArray< TLanguage >, const RArray< TUint32 >)
