Class virtual Lwt_engine.abstract
class virtual abstract : object..end
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 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
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.
