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 combine function is used to compose the materialized values of this flow and that flow into the materialized value of the resulting FlowTIn, TOut, TMat.
