Detailed Description

Encapsulation of device class definitions.

Contains a single TInt as member data and methods to extract the major, minor and service class information from that TInt.

Constructor & Destructor Documentation

TBTDeviceClass ( )

IMPORT_C

TBTDeviceClass

(

)

Constructor. Initialises the device class to 0.

TBTDeviceClass ( TUint32 )

IMPORT_C

TBTDeviceClass

(

TUint32

aDeviceClass

)

Constructor

Parameter	Description
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.

Parameter	Description
aMajorServiceClass	The major service class for the device.
aMajorDeviceClass	The major device class.
