Methods inherited from Cake\Core\ObjectRegistry

__debugInfo()source public

__debugInfo( )

Debug friendly object properties.

Returns

array

__get()source public

__get( string $name )

Provide public read access to the loaded objects

Parameters

string $name
Name of property to read

Returns

mixed

__isset()source public

__isset( string $name )

Provide isset access to _loaded

Parameters

string $name
Name of object being checked.

Returns

boolean

_checkDuplicate()source protected

_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.

Parameters

string $name
The name of the alias in the registry.
array $config
The config data for the new instance.

Throws

RuntimeException
When a duplicate is found.

get()source public

get( string $name )

Get loaded object instance.

Parameters

string $name
Name of object.

Returns

object|null
Object instance if loaded else null.

has()source public

has( string $name )

Check whether or not a given object is loaded.

Parameters

string $name
The object name to check for.

Returns

boolean
True is object is loaded else false.

load()source public

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.

Parameters

string $objectName
The name/class of the object to load.
array $config optional []
Additional settings to use when loading the object.

Returns

mixed

loaded()source public

loaded( )

Get the list of loaded objects.

Returns

array
List of object names.

normalizeArray()source public

normalizeArray( array $objects )

Normalizes an object array, creates an array that makes lazy loading easier

Parameters

array $objects
Array of child objects to normalize.

Returns

array
Array of normalized objects.

reset()source public

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()source public

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

Parameters

string $objectName
The name of the object to set in the registry.
object $object
instance to store in the registry

unload()source public

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.

Parameters

The name of the object to remove from the registry.
