Compare(const CUsbClassControllerBase &, const CUsbClassControllerBase &)

IMPORT_C TInt	Compare	(	const CUsbClassControllerBase &	aFirst,
			const CUsbClassControllerBase &	aSecond
		)	[static]

Compare Static function to compare two class controllers on the basis of their startup priorities.

Parameters

const CUsbClassControllerBase & aFirst	First class controller.
const CUsbClassControllerBase & aSecond	Second class controller.

DoCancel()

void

DoCancel

(

)

[pure virtual]

DoCancel Framework function.

GetDescriptorInfo(TUsbDescriptor &)

void

GetDescriptorInfo

(

TUsbDescriptor &

aDescriptorInfo

)

const [pure virtual]

GetDescriptorInfo Returns information on the class controller's descriptors.

Parameters

TUsbDescriptor & aDescriptorInfo

Structure to return information in.

Owner()

IMPORT_C MUsbClassControllerNotify &

Owner

(

)

const

Owner Fetch the owner of the USB class controller.

RunError(TInt)

TInt

RunError

(

TInt

aError

)

[pure virtual]

RunError

Parameters

TInt aError

The error with which RunL left.

RunL()

void

RunL

(

)

[pure virtual]

RunL Framework function. Class controllers are Active Objects, and may if relevant use that to register interfaces asynchronously.

Start(TRequestStatus &)

void

Start

(

TRequestStatus &

aStatus

)

[pure virtual]

Start Called by the server to get this class controller to register its interfaces.

Parameters

TRequestStatus & aStatus

TRequestStatus to signal completion of the request.

StartupPriority()

IMPORT_C TInt

StartupPriority

(

)

const

StartupPriority Get the startup priority of this USB class controller.

State()

IMPORT_C TUsbServiceState

State

(

)

const

State Get the state of this USB class controller.

Stop(TRequestStatus &)

void

Stop

(

TRequestStatus &

aStatus

)

[pure virtual]

Stop Called by the server to get this class controller to deregister its interfaces.

Parameters

TRequestStatus & aStatus

TRequestStatus to signal completion of the request.

Member Data Documentation

MUsbClassControllerNotify & iOwner

MUsbClassControllerNotify &

iOwner

[protected]

Owner.

const TInt iStartupPriority

const TInt

iStartupPriority

[protected]

The relative priority of this class controller. The class controllers are sorted using their priorities to determine what order to start them in.

TUsbServiceState iState

TUsbServiceState

iState

[protected]

The current service state. This must be kept up-to-date depending on whether this class controller's interfaces are registered or not.
