(PECL ev >= 0.2.0)
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.
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}
Readonly . true
if the watcher is active. false
otherwise.
User custom data associated with the watcher
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.
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.
