Member Function Documentation

◆ clone()

UnchangedDataSeriesMapper * clone ( ) const

overridevirtual

Note: Subclasses would normally return their own type rather than the Clonable type. The C++ language rules allow a more derived type to be returned from a virtual function and the compiler will still treat it as a valid override.

Application::Memento::Data * createMementoData ( const DataSeries & dataSeries ) const

overridevirtual

Parameters

dataSeries The model that will be used for mapping nodes to values.

Returns: A memento object which client code cannot do anything useful with except pass it around. The memento is ultimately only useful to the getValue() function. It holds internal data the mapper will use to perform the required mapping.

overridevirtual

Parameters

index	The index of the item being mapped.
srcValue	The value of the source data series at the specified index.
destValue	The mapped value should be assigned to this before returning.
mementoData	Must be the same object supplied by a previous call to createMementoData().

Returns: True if the srcValue could be mapped. If there was some kind of error, false should be returned and the caller should not attempt to continue mapping values.
