Class TBTDeviceClass

class TBTDeviceClass;

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.

Members

Defined in TBTDeviceClass:
DeviceClass(), ExternalizeL(), InternalizeL(), MajorDeviceClass(), MajorServiceClass(), MinorDeviceClass(), TBTDeviceClass(), TBTDeviceClass(), TBTDeviceClass(), operator=(), operator==()

IMPORT_C TBTDeviceClass();

Description

Constructor. Initialises the device class to 0.

IMPORT_C TBTDeviceClass(TUint32 aDeviceClass);

Description

Constructor

Parameters

TUint32 aDeviceClass The initial device class

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

Description

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

IMPORT_C TUint16 MajorServiceClass() const;

Description

Getter for major service class Currently we only support CoD format #1.

Return value

TUint16 The MajorServerClass

IMPORT_C TUint8 MajorDeviceClass() const;

Description

Getter for major device class Currently we only support CoD format #1.

Return value

TUint8 The MajorDeviceClass

IMPORT_C TUint8 MinorDeviceClass() const;

Description

Getter for minor device class Currently we only support CoD format #1.

Return value

TUint8 The MinorDeviceClass

IMPORT_C TUint32 DeviceClass() const;

Description

Getter for whole device class

Return value

TUint32 The DeviceClass

IMPORT_C TBool operator==(const TBTDeviceClass &aDeviceClass) const;

Description

Comparison operator

Parameters

const TBTDeviceClass &aDeviceClass the instance with which this is compared

Return value

TBool ETrue if device classes are equal, otherwise false

IMPORT_C TBTDeviceClass &operator=(const TBTDeviceClass &aDeviceClass);

Description

Assignment operator

Parameters

const TBTDeviceClass &aDeviceClass the instance from which this is assigned

Return value

TBTDeviceClass & this Device Class

IMPORT_C void ExternalizeL(RWriteStream &aStream) const;

Description

Extenalize this object to a stream.

Parameters

RWriteStream &aStream The stream object to which the class data will be written.

Leave codes

This method will leave if an error occurs.

IMPORT_C void InternalizeL(RReadStream &aStream);

Description

Internalize this object from a stream.

Parameters

RReadStream &aStream The stream object containing the data with which to internalize this object.

Leave codes

This method will leave if an error occurs.
