The EvWatcher class
Вернуться к: Ev
(PECL ev >= 0.2.0)
Введение
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.

Свойства
- is_active
-
Readonly .
TRUEif the watcher is active.FALSEotherwise. - data
-
User custom data associated with the watcher
- is_pending
-
Readonly .
TRUEif the watcher is pending, i.e. it has outstanding events, but its callback has not yet been invoked.FALSEotherwise. As long, as a watcher is pending(but not active), one must not change its priority. - priority
-
Integer between
Ev::MINPRIandEv::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.
