trait EventState[F[_], E, A] extends AnyRef

An atomic reference that can only be modified through a linear application of events. When you create one, all events are processed with the pre-supplied function you give it during construction. Then, on every call to doNext, the state is atomically updated and returned to you.

Abstract Value Members

  1. abstract def doNext(e: E): F[A]

    Applies the given event to this EventState and returns the new resulting state.

  2. abstract def get: F[A]

    Gets the current value of state.

  3. abstract def hookup: Pipe[F, E, A]

    Feeds a stream of events into this EventState, returning a new stream of all resulting states.

    Feeds a stream of events into this EventState, returning a new stream of all resulting states. The resulting stream should be equivalent to a stream of all changes in state unless there are multiple hookups. When in doubt, apply the Single Writer Principle and only use a single stream to apply updates unless this is not important.

  4. abstract def hookupWithInput: Pipe[F, E, (E, A)]

    The same as hookup, but also gives you the events passed through it as a tuple along with the resulting state.
