GetDevPropertyDescL(const TMTPDevicePropertyCode, MMTPType **)

TInt	GetDevPropertyDescL	(	const TMTPDevicePropertyCode	aPropCode,
			MMTPType **	aMMTPtype
		)	[pure virtual]

This interface method is designed to implement GetDevicePropDesc (Operation Code EMTPOpCodeGetDevicePropDesc). This operation returns the current property desc of the particular device property.

Parameters

const TMTPDevicePropertyCode aPropCode	: device property code eg: PlaybackObject(D411)
MMTPType ** aMMTPtype	: out param memory need to be allocated by the implementation. Owner ship of this param should be with allocator.

GetDevPropertyL(const TMTPDevicePropertyCode, MMTPType **)

TInt	GetDevPropertyL	(	const TMTPDevicePropertyCode	aPropCode,
			MMTPType **	aMMTPtype
		)	[pure virtual]

This interface method is designed to implement GetDevicePropValue (Operation Code EMTPOpCodeGetDevicePropValue). This operation returns the current value of the particular device property.

Parameters

const TMTPDevicePropertyCode aPropCode	: device property code eg: PlaybackObject(D411)
MMTPType ** aMMTPtype	: out param memory need to be allocated by the implementation. Owner ship of this param should be with allocator.

GetDevicePropertyContainerL(TMTPDevicePropertyCode, MMTPType **)

TInt	GetDevicePropertyContainerL	(	TMTPDevicePropertyCode	aPropCode,
			MMTPType **	aMMTPtype
		)	[pure virtual]

Parameters

TMTPDevicePropertyCode aPropCode
MMTPType ** aMMTPtype	: out param memory need to be allocated by the implementation. Owner ship of this param should be with allocator. SetDevicePropertyL function uses the allocated memory to set the device property when a EMTPOpCodeSetDevicePropValue operation code comes.

Supported(TMTPSupportCategory, RArray< TUint > &, TMTPOperationalMode)

void	Supported	(	TMTPSupportCategory	aCategory,
			RArray< TUint > &	aArray,
			TMTPOperationalMode	aMode
		)	[pure virtual]

This method returns the supported properties by extension plugin.

Parameters

TMTPSupportCategory aCategory
RArray< TUint > & aArray
TMTPOperationalMode aMode
