This interface is used togehter with the attribute BuildNewHandlerAttribute. It is possible to overwrite the default behavior when a new data item is created through the method New<(Of <<'(TData>)>>)()()()() To do this, you have to implement this interface and attach it to your IData type by using the attribute BuildNewHandlerAttribute

Examples
