type Tee a b c = Machine (T a b) c

A Machine that can read from two input stream in a deterministic manner.

type TeeT m a b c = MachineT m (T a b) c

A Machine that can read from two input stream in a deterministic manner with monadic side-effects.

data T a b c where

The input descriptor for a Tee or TeeT

Constructors

L :: T a b a

R :: T a b b

tee :: Monad m => ProcessT m a a' -> ProcessT m b b' -> TeeT m a' b' c -> TeeT m a b c

Compose a pair of pipes onto the front of a Tee.

addL :: Monad m => ProcessT m a b -> TeeT m b c d -> TeeT m a c d

Precompose a pipe onto the left input of a tee.

addR :: Monad m => ProcessT m b c -> TeeT m a c d -> TeeT m a b d

Precompose a pipe onto the right input of a tee.

capL :: Monad m => SourceT m a -> TeeT m a b c -> ProcessT m b c

Tie off one input of a tee by connecting it to a known source.

capR :: Monad m => SourceT m b -> TeeT m a b c -> ProcessT m a c

Tie off one input of a tee by connecting it to a known source.
