• CConverterBase

virtual void MaxSteps(TInt aMax, TInt aObject)=0;

Description

Gets the maximum number of steps that the conversion operation can take.

The conversion may complete in less than this number of steps (for example if an error occurs or the action is cancelled).

Each step is a call to CConverterBase::DoConvert(), although during synchronous conversions this is transparent to the client code.

Parameters

TInt aMax Maximum number of conversion steps TInt aObject Index that identifies an embedded object when one is being converted

virtual TInt Result(TInt aResult, TInt aObject)=0;

Description

Alerts the client to an error in conversion.

Parameters

TInt aResult A TResult value indicating the conversion state TInt aObject Index that identifies an embedded object when one is being converted

Return value

TInt A TAction value that indicates what action the converter should take

virtual HBufC* QueryPasswordL(const TDesC& aClue)=0;

Description

Queries the client for a password in order to access the data.

Parameters

const TDesC& aClue Data with a meaning is specific to each converter: it could for example indicate where the password is stored.

Return value

HBufC* Password entered

TAction

Description

Describes actions that the converter should take.

ERetain Keep already converted data. ERemove Delete converted data. ERepeat Reconvert data.

TResult

Description

Describes result of a conversion operation.

ESuccess Conversion succeeded. EPartialSuccess Conversion partially succeeded. EFailure Conversion failed.
