Abstract Value Members

  1. abstract def changed: Process[Task, Boolean]

    Permalink

    Returns a continuous stream, indicating whether the value has changed.

    Returns a continuous stream, indicating whether the value has changed. This will spike true once for each time the value of Signal was changed. It will always start with true when the process is run or when the Signal is set for the first time.

  2. abstract def changes: Process[Task, Unit]

    Permalink

    Returns the discrete version of changed.

    Returns the discrete version of changed. Will emit Unit when the value is changed.

  3. abstract def continuous: Process[Task, A]

    Permalink

    Returns the continuous version of this signal, always equal to the current A inside value.

    Returns the continuous version of this signal, always equal to the current A inside value. Note that this may not see all changes of A as it gets always current fresh A at every request.

  4. abstract def discrete: Process[Task, A]

    Permalink

    Returns the discrete version of this signal, updated only when value is changed.

    Returns the discrete version of this signal, updated only when value is changed. Value may change several times between reads, but it is guaranteed this will always get latest known value after any change. If you want to be notified about every single change use async.queue for signalling.

    It will emit the current value of the Signal after being run or when the signal is set for the first time
