Since

3.5.7

hasFinder()source 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

boolean

hasMethod()source 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

boolean

setTable()source public

setTable( Cake\ORM\Table $table )

Attaches a table instance to this registry.

Parameters

Cake\ORM\Table $table

The table this registry is attached to.

__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

__set()source public

__set( string $name , mixed $object )

Sets an object.

Parameters

string $name

Name of a property to set.

mixed $object

Object to set.

__unset()source public

__unset( string $name )

Unsets an object.

Parameters

string $name

Name of a property to unset.

_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.

count()source public

count( )

Returns the number of loaded objects.

Returns

integer

Implementation of

Countable::count()

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.

getIterator()source public

getIterator( )

Returns an array iterator.

Returns

ArrayIterator

Implementation of

IteratorAggregate::getIterator()

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

Throws

Exception
If the class cannot be found.

loaded()source public

loaded( )

Get the list of loaded objects.

Returns

string[]
List of object names.

normalizeArray()source public

Parameters

array $objects

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