TBTDeviceClass()

IMPORT_C

TBTDeviceClass

(

)

Constructor. Initialises the device class to 0.

TBTDeviceClass(TUint32)

IMPORT_C

TBTDeviceClass

(

TUint32

aDeviceClass

)

Constructor

Parameters

TUint32 aDeviceClass

The initial device class

TBTDeviceClass(TUint16, TUint8, TUint8)

IMPORT_C	TBTDeviceClass	(	TUint16	aMajorServiceClass,
			TUint8	aMajorDeviceClass,
			TUint8	aMinorDeviceClass
		)

Constructor taking separate fields for combination into device class

Construct a Class of Device using format #1 as per the baseband assigned numbers .

Note that this is a 24-bit field which we store in a 32-bit integer.

Parameters

TUint16 aMajorServiceClass	The major service class for the device.
TUint8 aMajorDeviceClass	The major device class.
TUint8 aMinorDeviceClass
