Constructor & Destructor Documentation

CLbtClientRequester(RLbt &)

CLbtClientRequester ( RLbt & aLbt ) [private]

C++ default constructor

Parameters

RLbt & aLbt

~CLbtClientRequester()

~CLbtClientRequester ( )

Destructor.

Member Functions Documentation

ConstructL()

void ConstructL ( ) [private]

Second phase constructor

DoCancel()

void DoCancel ( ) [private, virtual]

Implements cancellation of an outstanding request.

This function is called as part of the active object's Cancel() .

It must call the appropriate cancel function offered by the active object's asynchronous service provider. The asynchronous service provider's cancel is expected to act immediately.

DoCancel() must not wait for event completion; this is handled by Cancel() .

CActive::Cancel

ListTriggerData()

RPointerArray < CLbtTriggerInfo > * ListTriggerData ( )

ListTriggerIdData()

RArray < TLbtTriggerId > * ListTriggerIdData ( )

ListTriggersSize()

TInt & ListTriggersSize ( )

Returns reference of list trigger size.

NewL(RLbt &)

CLbtClientRequester * NewL ( RLbt & aLbt ) [static]

Construct a CLbtClientRequester object.

Parameters

RLbt & aLbt

RunError(TInt)

TInt RunError ( TInt aError ) [private, virtual]

Parameters

TInt aError

RunL()

void RunL ( ) [private, virtual]

Handles an active object's request completion event.

A derived class must provide an implementation to handle the completed request. If appropriate, it may issue another request.

The function is called by the active scheduler when a request completion event occurs, i.e. after the active scheduler's WaitForAnyRequest() function completes.

Before calling this active object's RunL() function, the active scheduler has:

1. decided that this is the highest priority active object with a completed request

2. marked this active object's request as complete (i.e. the request is no longer outstanding)

RunL() runs under a trap harness in the active scheduler. If it leaves, then the active scheduler calls RunError() to handle the leave.

Note that once the active scheduler's Start() function has been called, all user code is run under one of the program's active object's RunL() or RunError() functions.

SetBuffer(CBufFlat *)

void SetBuffer ( CBufFlat * aBuf )

Adds the buffer into the object.

Parameters

CBufFlat * aBuf

SetListTriggerData(RPointerArray< CLbtTriggerInfo > *)

void SetListTriggerData ( RPointerArray < CLbtTriggerInfo > * aTriggerInfoList )

Stores the list trigger data.

Parameters

RPointerArray < CLbtTriggerInfo > * aTriggerInfoList

SetListTriggerIdData(RArray< TLbtTriggerId > *)

void SetListTriggerIdData ( RArray < TLbtTriggerId > * aTriggerIdArray )

Stores the list trigger id data.

Parameters

RArray < TLbtTriggerId > * aTriggerIdArray

SetStatus(TRequestStatus &)

void SetStatus ( TRequestStatus & aStatus )

Stores the client's status.

Parameters

TRequestStatus & aStatus

Start()

void Start ( )

Starts the asyncronous operation by setting the iStatus to active

Start(TAsyncReqType)

void Start ( TAsyncReqType aType )

Starts the asyncronous operation by setting the iStatus to active.

Parameters

TAsyncReqType aType

Status()

TRequestStatus & Status ( )

Retrieves client's status
