Constructor & Destructor Documentation

CSmsuActiveBase(TInt)

IMPORT_C

CSmsuActiveBase

(

TInt

aPriority

)

[protected]

Constructor.

capability: None

Parameters

TInt aPriority

Active object priority

~CSmsuActiveBase()

IMPORT_C

~CSmsuActiveBase

(

)

Destructor.

capability: None

Member Functions Documentation

Complete(TInt)

IMPORT_C void

Complete

(

TInt

aStatus

)

[protected, virtual]

Object use complete.

This is called at the end of the RunL() , if the RunL() has not reset the object to be active.

If an observer has been set (see Queue() ), DoComplete() is called, and that observer is signalled with the object status.

capability: None

Parameters

TInt aStatus

Active object status word

CompleteMyself(TInt, TBool)

IMPORT_C void	CompleteMyself	(	TInt	aStatus,
			TBool	aSetActive = ETrue
		)	[protected]

Signals this object.

capability: None

Parameters

TInt aStatus	Status code with which to signal the object
TBool aSetActive = ETrue	True to set the object to be active

CompleteMyselfAfterTimeout(TInt)

IMPORT_C void

CompleteMyselfAfterTimeout

(

TInt

aStatus

)

[protected]

This function is used to request that the active object is completed after the current timeout is handled. When a timeout occurs, the active object is cancelled which requires DoCancel() to be called. However the object is active until after the DoCancel() meaning it is not possible to make a new request. This function requests a second call to Complete() (via RunL etc.) which is done without the object being active.

This function can only be called when a timeout occurs, otherwise it would not get actioned.

capability: None

Parameters

TInt aStatus

Status code with which to signal the object

ConstructTimeoutL()

IMPORT_C void

ConstructTimeoutL

(

)

[protected]

Constructs a timer.

This is required before use of TimedSetActive() .

capability: None

DoComplete(TInt &)

void

DoComplete

(

TInt &

)

[protected, inline, virtual]

Implements derived-class specified Complete() behaviour.

This is called from Complete() .

Parameters

TInt &

DoRunL()

void

DoRunL

(

)

[protected, pure virtual]

Implements derived-class specified RunL() behaviour.

This is called from RunL() .

Queue(TRequestStatus &)

IMPORT_C void

Queue

(

TRequestStatus &

aStatus

)

[protected]

Sets an asynchronous observer to which to report completion of this object.

capability: None

Parameters

TRequestStatus & aStatus

Asynchronous status word of the observer

RunError(TInt)

IMPORT_C TInt

RunError

(

TInt

aError

)

[protected, virtual]

Handles leaves occurring in the RunL() function.

It calls Complete() .

capability: None

Parameters

TInt aError

RunL() leave code

RunL()

IMPORT_C void

RunL

(

)

[protected, virtual]

Handles the object's request completion event.

If a timer has been set with TimedSetActive() , this is cancelled. DoRunL() is then called. If, after this, the object is not active, Complete() is called.

capability: None

TimedOut()

IMPORT_C TBool

TimedOut

(

)

const [protected]

Determines if the object has timed out.

TimedSetActive

TimedSetActive(const TTimeIntervalMicroSeconds32 &)

IMPORT_C void

TimedSetActive

(

const TTimeIntervalMicroSeconds32 &

aTimeIntervalMicroSeconds32

)

[protected]

Activates the object, and sets it to be completed after a specified time.

capability: None

Parameters

const TTimeIntervalMicroSeconds32 & aTimeIntervalMicroSeconds32

Time after which to complete the object

TimedSetActiveCancel()

IMPORT_C void

TimedSetActiveCancel

(

)

[protected]

Cancels a TimedSetActive() request.

TimedSetActive
