Method Detail
__construct() public ¶
__construct(?\Cake\ORM\Table $table)
Constructor
Parameters
-
\Cake\ORM\Table|null$table optional The table this registry is attached to.
__get() public ¶
__get(string $name)
Provide public read access to the loaded objects
Parameters
-
string$name Name of property to read
Returns
object|null__isset() public ¶
__isset(string $name)
Provide isset access to _loaded
Parameters
-
string$name Name of object being checked.
Returns
bool__set() public ¶
__set(string $name, mixed $object)
Sets an object.
Parameters
-
string$name Name of a property to set.
-
object$object Object to set.
__unset() public ¶
__unset(string $name)
Unsets an object.
Parameters
-
string$name Name of a property to unset.
_checkDuplicate() 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
RuntimeExceptionWhen a duplicate is found.
_create() protected ¶
_create(mixed $class, string $alias, array $config)
Create the behavior instance.
Part of the template method for Cake\Core\ObjectRegistry::load() Enabled behaviors will be registered with the event manager.
Parameters
-
string$class The classname that is missing.
-
string$alias The alias of the object.
-
array$config An array of config to use for the behavior.
Returns
\Cake\ORM\BehaviorThe constructed behavior class.
_getMethods() protected ¶
_getMethods(\Cake\ORM\Behavior $instance, string $class, string $alias)
Get the behavior methods and ensure there are no duplicates.
Use the implementedEvents() method to exclude callback methods.
Methods starting with _ will be ignored, as will methods
declared on Cake\ORM\Behavior
Parameters
-
\Cake\ORM\Behavior$instance The behavior to get methods from.
-
string$class The classname that is missing.
-
string$alias The alias of the object.
Returns
arrayA list of implemented finders and methods.
Throws
LogicExceptionwhen duplicate methods are connected.
_resolveClassName() protected ¶
_resolveClassName(string $class)
Resolve a behavior classname.
Part of the template method for Cake\Core\ObjectRegistry::load()
Parameters
-
string$class Partial classname to resolve.
Returns
string|nullEither the correct class name or null.
_throwMissingClassError() protected ¶
_throwMissingClassError(string $class, ?string $plugin)
Throws an exception when a behavior is missing.
Part of the template method for Cake\Core\ObjectRegistry::load() and Cake\Core\ObjectRegistry::unload()
Parameters
-
string$class The classname that is missing.
-
string|null$plugin The plugin the behavior is missing in.
Throws
Cake\ORM\Exception\MissingBehaviorExceptioncall() public ¶
call(string $method, array $args)
Invoke a method on a behavior.
Parameters
-
string$method The method to invoke.
-
array$args optional The arguments you want to invoke the method with.
Returns
mixedThe return value depends on the underlying behavior method.
Throws
BadMethodCallExceptionWhen the method is unknown.
callFinder() public ¶
callFinder(string $type, array $args)
Invoke a finder on a behavior.
Parameters
-
string$type The finder type to invoke.
-
array$args optional The arguments you want to invoke the method with.
Returns
\Cake\ORM\QueryThe return value depends on the underlying behavior method.
Throws
BadMethodCallExceptionWhen the method is unknown.
className() public static ¶
className(string $class)
Resolve a behavior classname.
Parameters
-
string$class Partial classname to resolve.
Returns
string|nullEither the correct classname or null.
dispatchEvent() public ¶
dispatchEvent(string $name, ?array $data, ?object $subject)
Wrapper for creating and dispatching events.
Returns a dispatched event.
Parameters
-
string$name Name of the event.
-
array|null$data optional Any value you wish to be transported with this event to it can be read by listeners.
-
object|null$subject optional The object that this event applies to ($this by default).

\Cake\Event\EventInterfaceget() public ¶
get(string $name)
Get loaded object instance.
Parameters
-
string$name Name of object.
Returns
objectObject instance.
Throws
RuntimeExceptionIf not loaded or found.
getEventManager() public ¶
getEventManager()
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.
Returns
\Cake\Event\EventManagerInterfacehas() public ¶
has(string $name)
Check whether or not a given object is loaded.
Parameters
-
string$name The object name to check for.
Returns
boolTrue is object is loaded else false.
hasFinder() public ¶
hasFinder(string $method)
Check if any loaded behavior implements the named finder.
Will return true if any behavior provides a public method with the chosen name.
Parameters
-
string$method The method to check for.
Returns
boolhasMethod() public ¶
hasMethod(string $method)
Check if any loaded behavior implements a method.
Will return true if any behavior provides a public non-finder method with the chosen name.
Parameters
-
string$method The method to check for.
Returns
boolload() 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
mixedThrows
ExceptionIf the class cannot be found.

-
array$objects Array of child objects to normalize.
Returns

Returns
$thissetEventManager() public ¶
setEventManager(\Cake\Event\EventManagerInterface $eventManager)
