Iteratee

An Iteratee represents a computation over a stream of data.

At each step, the Iteratee receives a stream element of type I. It can then either signal that processing the stream should continue by returning a Left containing another Iteratee of the same type, or that processing is finished by returning a value of type O.

Classical iteratees always work on infinite streams. These, however, can be used on finite ones. At the end of the stream, if the Iteratee has not already signalled that processing should terminate, its endOfInput method is called to produce the final value.

Abstract Value Members

abstract def endOfInput(): O

Signals that there will be no more data forthcoming.
Signals that there will be no more data forthcoming. The Iteratee must now produce its final value.
returns
The output of this Iteratee.
abstract def process(input: I): Either[Iteratee[I, O], O]

Consume one piece of input.
Consume one piece of input. If the computation is not finished, a new Iteratee is returned.
input
The data to consume.
returns
Either a new Iteratee or the final result.
