Members

Defined in MCHFDataSupplierObserver:


Member functions


ReceivedCompleteL(TInt)

virtual void ReceivedCompleteL(TInt aCompleteCode)=0;

Description

Called to report data supplier status.

It is usually called when the data supplier acquires a chunk of data or an error condition is encountered in the process. This method MUST only be used to report back on an asynchronous activity.

Parameters

TInt aCompleteCode

KErrNone or any system error code.


DSRunError(TInt)

virtual TInt DSRunError(TInt aError)=0;

Description

Called to report error conditions.

This is usually under circumstances where MCHFDataSupplierObserver::ReceivedCompleteL(TInt) is inappropriate because of being a leave method. The same condition of use as MCHFDataSupplierObserver::ReceivedCompleteL(TInt) applies.

Parameters

TInt aError

Any system error code

Return value

TInt

KErrNone as acknowledgement of having dealt with the error condition, otherwise an error code. Note that a return other than KErrNone could cause a panic.
