Constructor & Destructor Documentation

RSwiObserverSession()

IMPORT_C RSwiObserverSession ( )

This constructor provides a single point of definition from which the superclass constructor is called.

Member Functions Documentation

AddEventL(const CObservationData &)

IMPORT_C void AddEventL ( const CObservationData & aData )

Writes an observed SWI event into the shared log file about the file changed by the SWI operation.

Parameters

const CObservationData & aData The observed SWI event.

AddHeaderL(const CObservationHeader &)

IMPORT_C void AddHeaderL ( const CObservationHeader & aHeader )

Writes a SWI observation header into the shared log file about the file changed by the SWI operation.

Parameters

const CObservationHeader & aHeader The observation header.

CancelRegistration()

IMPORT_C void CancelRegistration ( )

Cancels the registration request. This function has no effect if there is no outstanding request.

Close()

IMPORT_C void Close ( )

Closes the SWI Observer connection.

CommitL()

IMPORT_C void CommitL ( )

Notifies the SWI Observer that the SWI operation has been finished successfully.

Connect()

IMPORT_C TInt Connect ( )

Connect to the SWI Observer.

GetFileHandleL(TDes &)

IMPORT_C void GetFileHandleL ( TDes & aFileName )

Requests a file handle from the SWI Observer. Having created a log file (e.g. 1.swi) under its own private folder, the SWI Observer shares the file handle with the process where an instance of this class is working.

Parameters

TDes & aFileName The fully qualified name of the file whose handle was sent by the SWI Observer.

ProcessLogsL(RFs &)

IMPORT_C void ProcessLogsL ( RFs & aFs )

Checks the SWI Observer's flag file to find out if there are some log files to process. If that's the case, it starts up the SWI Observer, if not, then it returns without doing anything.

Parameters

RFs & aFs The file server session handle.

Register(TRequestStatus &)

IMPORT_C void Register ( TRequestStatus & aStatus )

Registers to the SWI Observer. If the SWI Observer processor is busy, the server completes the client when the processor becomes idle.

Parameters

TRequestStatus & aStatus The SWI Observer completes this request object when the SWI Observer Processor becomes idle.
