はじめに

EvWatcher is a base class for all watchers( EvCheck , EvChild etc.). Since EvWatcher 's constructor is abstract , one can't(and don't need to) create EvWatcher objects directly.


クラス概要


abstract EvWatcher {

/* プロパティ */

public $is_active

public $data

public $is_pending

public $priority

/* メソッド */

public clear ( ) : int

abstract public __construct ( )

public feed ( int $revents ) : void

public getLoop ( ) : EvLoop

public invoke ( int $revents ) : void

public keepalive ([ bool $value ] ) : bool

public setCallback ( callable $callback ) : void

public start ( ) : void

public stop ( ) : void

}

プロパティ

is_active
Readonly . true if the watcher is active. false otherwise.
data
User custom data associated with the watcher
is_pending
Readonly .true if the watcher is pending, i.e. it has outstanding events, but its callback has not yet been invoked. false otherwise. As long, as a watcher is pending(but not active), one must not change its priority.
priority
int between Ev::MINPRI and Ev::MAXPRI . Pending watchers with higher priority will be invoked before watchers with lower priority, but priority will not keep watchers from being executed(except for EvIdle watchers). EvIdle watchers provide functionality to suppress invocation when higher priority events are pending.
