CA3FDevSoundAdaptationInfo Class Reference

class CA3FDevSoundAdaptationInfo : public CBase

An interface to a A3FDevsoundAdaptationInfo. A3FDevSoundAdaptationInfo is a replacable component that should correspond to the underlying A3F adaptation, and provides information to the DevSound Adaptor information it cannot otherwise obtain. If the underlying A3F adaptation changes, then potentially so should the implementation of A3FDevSoundAdaptationInfo. Additionally the MaxGain and MaxVolume values should be set to reflect those required for the specific product. devsoundadaptationinfo.lib

Member Functions Documentation

IsResumeSupported(TUid, TUid)

TBool	IsResumeSupported	(	TUid	aCodecType,
			TUid	aFormat
		)	[inline]

Queries A3F adaptation about if True Pause is supported the completion will be indicated by RequestSupportedFormatsComplete().

Parameters

TUid aCodecType	KUidAudioEncoder for encoder format, KUidAudioDecoder for decoder format
TUid aFormat	The format to be queried

NewL(MA3FDevSoundAdaptationInfoObserver &, CFourCCConvertor &)

IMPORT_C CA3FDevSoundAdaptationInfo *	NewL	(	MA3FDevSoundAdaptationInfoObserver &	aAdaptationInfoObserver,
			CFourCCConvertor &	aFourCcConvertor
		)	[static]

Constructs and returns a pointer to a new CA3FDevSoundAdaptationInfo object. Leaves on failure.

Parameters

MA3FDevSoundAdaptationInfoObserver & aAdaptationInfoObserver
CFourCCConvertor & aFourCcConvertor

RequestMaxGain(TUid)

TInt

RequestMaxGain

(

TUid

aCodecType

)

[pure virtual]

Requests Maximun Valid Gain/Volume. This is an asynchronous call. If error return is KErrNone, the result will be returned in subsequent RequestMaxGainComplete() call.

Parameters

TUid aCodecType

KUidAudioEncoder for MaxGain, KUidAudioDecoder for MaxVolume

RequestSupportedFormats(TUid, RArray< TUid > &)

TInt	RequestSupportedFormats	(	TUid	aCodecType,
			RArray< TUid > &	aSupportedFormats
		)	[pure virtual]

Requests a list of supported FourCC codes. This is an asynchronous call. If error return is KErrNone, the completion will be indicated by RequestSupportedFormatsComplete().

Parameters

TUid aCodecType	KUidAudioEncoder for supported encoder formats, KUidAudioDecoder for supported decoder formats
RArray< TUid > & aSupportedFormats	The results are appended to this array.
