Add the given Flow as the final step in a bidirectional transformation pipeline. By convention protocol stacks are growing to the left: the right most is the bottom layer, the closest to the metal. {{{ +---------------------------+ | Resulting Flow | | | | +------+ +------+ | I1 ~~> | | ~O1~> | | | | | this | | flow | | O2 <~~ | | <~I2~ | | | | +------+ +------+ | +---------------------------+ }}} The materialized value of the combined Flow< TIn, TOut, TMat> will be the materialized value of the current flow (ignoring the other Flow’s value), use JoinMat< TMat2, TMat3> (Flow< TOut1, TIn2, TMat2> , Func< TMat, TMat2, TMat3> ) if a different strategy is needed.
