Class `Lwt_engine.abstract`Source

Abstract class for engines.

method destroy : unit

Destroy the engine, remove all its events and free its associated resources.

method transfer : abstract -> unit

transfer engine moves all events from the current engine to engine. Note that timers are reset in the destination engine, i.e. if a timer with a delay of 2 seconds was registered 1 second ago it will occur in 2 seconds in the destination engine.

Event loop methods

method virtual iter : bool -> unit

method fork : unit

method on_readable : Unix.file_descr -> (event -> unit) -> event

method on_writable : Unix.file_descr -> (event -> unit) -> event

method on_timer : float -> bool -> (event -> unit) -> event

method fake_io : Unix.file_descr -> unit

method readable_count : int

method writable_count : int

method timer_count : int

method forwards_signal : int -> bool

Backend methods

Notes:

the callback passed to register methods is of type unit -> unit and not event -> unit
register methods return a lazy value which unregisters the event when forced

method private virtual cleanup : unit

Cleanup resources associated with the engine.

method private virtual register_readable : Unix.file_descr ->
  (unit -> unit) ->
  unit Lazy.t

method private virtual register_writable : Unix.file_descr ->
  (unit -> unit) ->
  unit Lazy.t

method private virtual register_timer : float ->
  bool ->
  (unit -> unit) ->
  unit Lazy.t
