Member Functions Documentation

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 CConverterBase2::DoConvert(), although during synchronous conversions this is transparent to the client code.

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