# The EvWatcher class

(PECL ev >= 0.2.0)

## 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

abstract EvWatcher {
/* Properties */
public $is_active ;
public $data ;
public $is_pending ;
public $priority ;
/* Methods */
public int clear ( void )
abstract public __construct ( void )
public void feed ( int `$revents` )
public EvLoop getLoop ( void )
public void invoke ( int `$revents` )
public bool keepalive ([ bool `$value` ] )
public void setCallback ( callable `$callback` )
public void start ( void )
public void stop ( void )
}

## Properties

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

  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 functionality to suppress invocation when higher priority events are pending.
