IterateeT

sealed abstract class IterateeT[E, F[_], A] extends AnyRef

A data sink.

Represents a value of type F[StepT[E, F, A]]

E

The type of the input data (mnemonic: Element type)

F

The type constructor representing an effect. The type constructor scalaz.Id is used to model pure computations, and is fixed as such in the type alias scalaz.iteratee.Iteratee.

A

The type of the calculated result

    Combine this Iteratee with an Enumerator-like function.

    Combine this Iteratee with an Enumerator-like function.

    Often used in combination with the implicit views such as enumStream and enumIterator, for example:

    head[Unit, Int, Id] >>== Stream.continually(1) // enumStream(Stream.continually(1))
    f

    An Enumerator-like function. If the type parameters EE and BB are chosen to be E and B respectively, the type of f is equivalent to EnumeratorT[E, F, A].

  9. def advance[EE, AA, G[_]](f: (StepT[E, F, A]) ⇒ IterateeT[EE, G, AA])(implicit MO: |>=|[G, F]): IterateeT[EE, G, AA]

    A generalization of >>== that allows a step function which returns its result in a different, "bigger" monad.

    A generalization of >>== that allows a step function which returns its result in a different, "bigger" monad. The monad for G must perform all the effects of F as part of its evaluation; in the trivial case, of course F and G will have the same monad.
