_checkDuplicatesource 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.

getsource public

get( string $name )

Get loaded object instance.

Parameters

string $name

Name of object.

Returns

object|null
Object instance if loaded else null.

hassource 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.

loadsource 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
mixed

loadedsource public

loaded( )

Returns

array
Array of normalized objects.

If the registry subclass has an event manager, the objects will be detached from events as well.

setsource public
