Method Detail
__construct() ¶ public
__construct(Cake\ORM\Table|null $table = null)
Constructor
Parameters
-
Cake\ORM\Table|null
$table optional The table this registry is attached to.
__get() ¶ public
__get(string $name): mixed
Provide public read access to the loaded objects
Parameters
-
string
$name Name of property to read
Returns
mixed
__isset() ¶ public
__isset(string $name): bool
Provide isset access to _loaded
Parameters
-
string
$name Name of object being checked.
Returns
bool
__set() ¶ public
__set(string $name, mixed $object): void
Sets an object.
Parameters
-
string
$name Name of a property to set.
-
mixed
$object Object to set.

void
__unset() ¶ public
__unset(string $name): void
Unsets an object.
Parameters
-
string
$name Name of a property to unset.
Returns
void
_checkDuplicate() ¶ protected
_checkDuplicate(string $name, array $config): void
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.
Returns
void
Throws
RuntimeException
When a duplicate is found.

string

Returns
Cake\ORM\Behavior
_getMethods() ¶ protected
_getMethods(Cake\ORM\Behavior $instance, string $class, string $alias): array
Get the behavior methods and ensure there are no duplicates.
Use the implementedEvents() method to exclude callback methods.

declared on Cake\ORM\Behavior
Parameters
-
Cake\ORM\Behavior
$instance The behavior to get methods from.
-
string
$class The classname that is missing.
-
string
$alias The alias of the object.

when duplicate methods are connected.
_resolveClassName() ¶ protected

has(string $name): bool
Check whether or not a given object is loaded.

-
string
$name The object name to check for.

Returns
bool
hasMethod() ¶ public
hasMethod(string $method): bool
Check if any loaded behavior implements a method.

bool
load() ¶ public
load(string $objectName, array $config = []): mixed
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.

mixed
