Transform this IFlow< TOut, TMat> by appending the given processing steps. The materialized value of the combined IFlow< TOut, TMat> will be the materialized value of the current flow (ignoring the other flow’s value), use ViaMaterialized< T2, TMat2, TMat3> (IGraph< FlowShape< TOut, T2> , TMat2> , Func< TMat, TMat2, TMat3> ) if a different strategy is needed.
