Property Details

enabled property
public boolean getEnabled()
public void setEnabled(boolean $value)

whether this behavior is enabled

owner property read-only
public CComponent getOwner()

the owner component that this behavior is attached to.

Method Details

attach() method
public void attach(CComponent $owner)
$owner CComponent the component that this behavior is to be attached to.
Source Code: framework/base/CBehavior.php#43 (show)
public function attach($owner)
{
    $this->_owner=$owner;
    foreach($this->events() as $event=>$handler)
        $owner->attachEventHandler($event,array($this,$handler));
}

Attaches the behavior object to the component. The default implementation will set the owner property and attach event handlers as declared in events. Make sure you call the parent implementation if you override this method.

detach() method
public void detach(CComponent $owner)
$owner CComponent the component that this behavior is to be detached from.
Source Code: framework/base/CBehavior.php#57 (show)
public function detach($owner)
{
    foreach($this->events() as $event=>$handler)
        $owner->detachEventHandler($event,array($this,$handler));
    $this->_owner=null;
}

Detaches the behavior object from the component. The default implementation will unset the owner property and detach event handlers declared in events. Make sure you call the parent implementation if you override this method.

events() method
public array events()
{return} array events (array keys) and the corresponding event handler methods (array values).
Source Code: framework/base/CBehavior.php#31 (show)
public function events()
{
    return array();
}

Declares events and the corresponding event handler methods. The events are defined by the owner component, while the handler methods by the behavior class. The handlers will be attached to the corresponding events when the behavior is attached to the owner component; and they will be detached from the events when the behavior is detached from the component.

getEnabled() method
public boolean getEnabled()
{return} boolean whether this behavior is enabled
Source Code: framework/base/CBehavior.php#75 (show)
public function getEnabled()
{
    return $this->_enabled;
}

getOwner() method
public CComponent getOwner()
{return} CComponent the owner component that this behavior is attached to.
Source Code: framework/base/CBehavior.php#67 (show)
public function getOwner()
{
    return $this->_owner;
}

setEnabled() method
public void setEnabled(boolean $value)
$value boolean whether this behavior is enabled
Source Code: framework/base/CBehavior.php#83 (show)
public function setEnabled($value)
{
    $this->_enabled=$value;
}
