ComponentRegistry is a registry for loaded components
Handles loading, constructing and binding events for component class objects.
$_Controller protected __construct( Cake\Controller\Controller $controller = null )
Constructor.
Cake\Controller\Controller $controller optional null _create( string $class , string $alias , array $config )
Create the component instance.
Part of the template method for Cake\Core\ObjectRegistry::load() Enabled components will be registered with the event manager.
$class $alias $config Cake\Controller\Component_resolveClassName( string $class )
Resolve a component classname.
Part of the template method for Cake\Core\ObjectRegistry::load()
$class _throwMissingClassError( string $class , string $plugin )
Throws an exception when a component is missing.
Part of the template method for Cake\Core\ObjectRegistry::load() and Cake\Core\ObjectRegistry::unload()
$class $plugin Cake\Controller\Exception\MissingComponentExceptiongetController( )
Get the controller associated with the collection.
Cake\Controller\ControllersetController( Cake\Controller\Controller $controller )
Set the controller associated with the collection.
Cake\Controller\Controller $controller __get( string $name )
Provide public read access to the loaded objects
$name __isset( string $name )
Provide isset access to _loaded
$name __set( string $name , mixed $object )
Sets an object.
$name $object __unset( string $name )
Unsets an object.
$name _checkDuplicate( string $name , array $config )
Check for duplicate object loading.
If a duplicate is being loaded and has different configuration, that is bad and an exception will be raised.
An exception is raised, as replacing the object will not update any references other objects may have. Additionally, simply updating the runtime configuration is not a good option as we may be missing important constructor logic dependent on the configuration.
$name $config count( )
Returns the number of loaded objects.
Countable::count() get( string $name )
Get loaded object instance.
$name getIterator( )
Returns an array iterator.
IteratorAggregate::getIterator() has( string $name )
Check whether or not a given object is loaded.
$name load( string $objectName , array $config = [] )
Loads/constructs an object instance.
Will return the instance in the registry if it already exists. If a subclass provides event support, you can use $config['enabled'] = false to exclude constructed objects from being registered for events.
Using Cake\Controller\Controller::$components as an example. You can alias an object by setting the 'className' key, i.e.,
public $components = [
'Email' => [
'className' => '\App\Controller\Component\AliasedEmailComponent'
];
]; All calls to the Email component would use AliasedEmail instead.
$objectName $config optional [] loaded( )
Get the list of loaded objects.
normalizeArray( array $objects )
Normalizes an object array, creates an array that makes lazy loading easier
$objects reset( )
Clear loaded instances in the registry.
If the registry subclass has an event manager, the objects will be detached from events as well.
set( string $objectName , object $object )
Set an object directly into the registry by name.
If this collection implements events, the passed object will be attached into the event manager
$objectName $object unload( string $objectName )
Remove an object from the registry.
If this registry has an event manager, the object will be detached from any events as well.
$objectName dispatchEvent( string $name , array|null $data = null , object|null $subject = null )
Wrapper for creating and dispatching events.
Returns a dispatched event.
$name $data optional null Any value you wish to be transported with this event to it can be read by listeners.
$subject optional null The object that this event applies to ($this by default).
Cake\Event\EventeventManager( Cake\Event\EventManager $eventManager = null )
Returns the Cake\Event\EventManager manager instance for this object.
You can use this instance to register any new listeners or callbacks to the object events, or create your own events and trigger them at will.
Cake\Event\EventManager $eventManager optional null Cake\Event\EventManagergetEventManager( )
Returns the Cake\Event\EventManager manager instance for this object.
You can use this instance to register any new listeners or callbacks to the object events, or create your own events and trigger them at will.
Cake\Event\EventManagersetEventManager( Cake\Event\EventManager $eventManager )
Returns the Cake\Event\EventManager manager instance for this object.
You can use this instance to register any new listeners or callbacks to the object events, or create your own events and trigger them at will.
Cake\Event\EventManager $eventManager getEventManager() |
protected Cake\Controller\Controller
The controller that this collection was initialized with.
