The EvWatcher class

INTRODUCTION

       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.

CLASS SYNOPSIS

       EvWatcher

       abstract
       EvWatcher

       Properties

       o public$is_active

       o public$data

       o public$is_pending

       o public$priority

       Methods

       o public int EvWatcher::clear (void  )

       o abstractpublic EvWatcher::__construct (void  )

       o public void EvWatcher::feed (int  $revents)

       o public EvLoop EvWatcher::getLoop (void  )

       o public void EvWatcher::invoke (int  $revents)

       o public bool EvWatcher::keepalive ([bool  $value])

       o public void EvWatcher::setCallback (callable  $callback)

       o public void EvWatcher::start (void  )

       o public void EvWatcher::stop (void  )

PROPERTIES

	      o $is_active
		- Readonly .  TRUE if the watcher is active.  FALSE otherwise.

	      o $data
		- User custom data associated with the watcher

	      o $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.

	      o $priority
		-  Integer  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 functional-
		ity to suppress invocation when higher priority events are pending.
