Observer interface for data suppliers.
Defined in MCHFDataSupplierObserver
:

Called to report error conditions.MCHFDataSupplierObserver_Reserved_1()
MCHFDataSupplierObserver_Reserved_2()
MCHFDataSupplierObserver_Reserved_3()
MCHFDataSupplierObserver_Reserved_4()
ReceivedCompleteL(TInt)
Called to report data supplier status.virtual void ReceivedCompleteL(TInt aCompleteCode)=0;
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.
|
virtual TInt DSRunError(TInt aError)=0;
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.
