Module CCTimerSource

Event timer

Used to be part of CCFuture.

Sourcetype t

A scheduler for events. It runs in its own thread.

Sourceval create : unit -> t

A new timer.

Sourceval set_exn_handler : t -> (exn -> unit) -> unit

set_exn_handler timer f registers f so that any exception raised by a task scheduled in timer is given to f.

Sourceexception Stopped
Sourceval after : t -> float -> f:(unit -> _) -> unit

Call the callback f after the given number of seconds.

  • raises Stopped

    if the timer was stopped.

Sourceval at : t -> float -> f:(unit -> _) -> unit

Create a future that evaluates to () at the given Unix timestamp.

  • raises Stopped

    if the timer was stopped.

Sourceexception ExitEvery
Sourceval every : ?delay:float -> t -> float -> f:(unit -> _) -> unit

every timer n ~f calls f () every n seconds. f() can raise ExitEvery to stop the cycle.

  • parameter delay

    if provided, the first call to f () is delayed by that many seconds.

  • raises Stopped

    if the timer was stopped.

Sourceval stop : t -> unit

Stop the given timer, cancelling pending tasks. Idempotent. From now on, calling most other operations on the timer will raise Stopped.

Sourceval active : t -> bool

Return true until stop t has been called.
