Debouncer

class Debouncer extends AnyRef

Highly performant generic debouncer

Note: This is not written as an Actor for performance reasons. Debounced calls are filtered synchronously, in the caller thread, without the need for locks, context switches, or heap allocations. We use AtomicBoolean to resolve concurrent races; the probability of contending on an AtomicBoolean transition is very low.

Instance Constructors

  1. new Debouncer(name: String, scheduler: SchedulerLike, delay: FiniteDuration, maxDelay: FiniteDuration, action: () ⇒ Unit, debounceFirst: Boolean = true, clock: Clock = java.time.Clock.systemUTC())

    name

    The name of this debouncer

    scheduler

    The scheduler implementation to use; Can accept an akka scheduler a la magnet pattern

    delay

    The time after which to invoke action; each time Debouncer.call is invoked, this delay is reset

    maxDelay

    The maximum time to delay the invocation of action()

    action

    The action to invoke

    debounceFirst

    If false, then the first invocation of call() calls action exactly once. Subsequent calls are debounced.
