Signal

Abstract Value Members

abstract def changed: Process[Task, Boolean]

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.

Signal
abstract def changes: Process[Task, Unit]

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

Signal
abstract def compareAndSet(f: (Option[A]) ⇒ Option[A]): Task[Option[A]]

Asynchronously sets the current value of this Signal and returns new value os this Signal.
Asynchronously sets the current value of this Signal and returns new value os this Signal. If this Signal has not been set yet, the Task will return None and value is set. If this Signal is finished Task will fail with End exception. If this Signal is failed Task will fail with Signal failure exception.
Furthermore if f results in evaluating to None, this Task is no-op and will return current value of the Signal.
abstract def continuous: Process[Task, A]

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.

Definition Classes
Signal
abstract def discrete: Process[Task, A]

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

Definition Classes
Signal
abstract def get: Task[A]

Asynchronously get the current value of this Signal
abstract def getAndSet(a: A): Task[Option[A]]

Asynchronously sets the current value of this Signal and returns previous value of the Signal.
Asynchronously sets the current value of this Signal and returns previous value of the Signal. If this Signal has not been set yet, the Task will return None and value is set. If this Signal is finished Task will fail with End exception. If this Signal is failed Task will fail with Signal failure exception.
abstract def set(a: A): Task[Unit]

Sets the value of this Signal.
abstract def sink: Sink[Task, Msg[A]]

Returns sink that can be used to set this signal
