Tags
Return values
Traversablehas()
Check whether a given object is loaded.
public
has(string $name) : bool
Parameters
- $name : string
-
The object name to check for.
Return values
bool —True is object is loaded else false.
hasFinder()
Check if any loaded behavior implements the named finder.
public
hasFinder(string $method) : bool
Will return true if any behavior provides a public method with the chosen name.
Parameters
- $method : string
-
The method to check for.
Return values
boolhasMethod()
Check if any loaded behavior implements a method.
public
hasMethod(string $method) : bool
Will return true if any behavior provides a public non-finder method with the chosen name.

Return values
boolload()
Loads/constructs an object instance.
public
load(string $name[, array<string, mixed> $config = [] ]) : mixed
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 as an example. You can alias an object by setting the 'className' key, i.e.,
protected $components = [
'Email' => [
'className' => 'App\Controller\Component\AliasedEmailComponent'
];
];
All calls to the Email
component would use AliasedEmail
instead.
Parameters
- $name : string
-
The name/class of the object to load.
- $config : array<string, mixed> = []
-
Additional settings to use when loading the object.
Tags

Parameters
- $objects : array<string|int, mixed>
-
Array of child objects to normalize.
Return values
array<string, array<string|int, mixed>> —Array of normalized objects.

public
reset() : $this
If the registry subclass has an event manager, the objects will be detached from events as well.
Return values
$thisset()

public
set(string $name, object $object) : $this
If this collection implements events, the passed object will be attached into the event manager
Parameters

-
instance to store in the registry
Tags
Return values
$thissetEventManager()

public
setEventManager(EventManagerInterface $eventManager) : $this
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.
Parameters
- $eventManager : EventManagerInterface
-
the eventManager to set
Return values
$thissetTable()
Attaches a table instance to this registry.
public
setTable(Table $table) : void
Parameters
- $table : Table
-
The table this registry is attached to.
unload()
Remove an object from the registry.
public
unload(string $name) : $this

Tags
Return values
$this_checkDuplicate()
Check for duplicate object loading.
protected
_checkDuplicate(string $name, array<string, mixed> $config) : void
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
- $name : string
-
The name of the alias in the registry.
- $config : array<string, mixed>
-
The config data for the new instance.
Tags
_create()
Create the behavior instance.

_getMethods()
Get the behavior methods and ensure there are no duplicates.
protected
_getMethods(Behavior $instance, string $class, string $alias) : array<string|int, mixed>
Use the implementedEvents() method to exclude callback methods.

will be ignored, as will methods
declared on Cake\ORM\Behavior
