Transform this IFlowTOut, TMat by appending the given processing steps. The materialized value of the combined IFlowTOut, TMat will be the materialized value of the current flow (ignoring the other flow’s value), use ViaMaterializedT2, TMat2, TMat3(IGraphFlowShapeTOut, T2, TMat2, FuncTMat, TMat2, TMat3) if a different strategy is needed.
