Method Detail
__construct() ¶ public
__construct(array $config = [])
Constructor
Parameters
-
array
$config optional Configuration
__debugInfo() ¶ public
__debugInfo(): array<string, mixed>
Debug friendly object properties.
Returns
array<string, mixed>
__get() ¶ public
__get(string $name): object|null
Provide public read access to the loaded objects
Parameters
-
string
$name Name of property to read
Returns
object|null
__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, object $object): void
Sets an object.
Parameters
-
string
$name Name of a property to set.
-
object
$object Object to set.
Returns
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<string, mixed> $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<string, mixed>
$config The config data for the new instance.
Returns
void
Throws
RuntimeException
When a duplicate is found.

Parameters
-
string|null
$key Key to read.
Returns
mixed
_configWrite() ¶ protected
_configWrite(array<string, mixed>|string $key, mixed $value, string|bool $merge = false): void
Writes a config key.
Parameters
-
array<string, mixed>|string
$key Key to write to.
-
mixed
$value Value to write.
-
string|bool
$merge optional True to merge recursively, 'shallow' for simple merge, false to overwrite, defaults to false.

void
Throws
Cake\Core\Exception\CakeException
if attempting to clobber existing config
_create() ¶ abstract protected
_create(object|string $class, string $alias, array<string, mixed> $config): object
Create an instance of a given classname.
This method should construct and do any other initialization logic required.

$plugin The plugin $class is missing from.
Returns
void
Throws
Exception
configShallow() ¶ public
configShallow(array<string, mixed>|string $key, mixed|null $value = null): $this
Merge provided config with existing config. Unlike config()
which does
a recursive merge for nested keys, this method does a simple merge.
Setting a specific value:
$this->configShallow('key', $value);
Setting a nested value:
$this->configShallow('some.nested.key', $value);
Updating multiple config settings at the same time:
$this->configShallow(['one' => 'value', 'another' => 'value']);
Parameters
-
array<string, mixed>|string
$key The key to set, or a complete array of configs.
-
mixed|null
$value optional The value to set.
Returns
$this
get() ¶ public
get(string $name): object
Get loaded object instance.
Parameters
-
string
$name Name of object.
Returns
object
Throws
RuntimeException
If not loaded or found.
getConfig() ¶ public
getConfig(string|null $key = null, mixed $default = null): mixed
Returns the config.
Usage
Reading the whole config:
$this->getConfig();
Reading a specific value:
$this->getConfig('key');
Reading a nested value:
$this->getConfig('some.nested.key');
Reading with default value:
$this->getConfig('some-key', 'default-value');
Parameters
-
string|null
$key optional The key to get or null for the whole config.
-
mixed
$default optional The return value when the key does not exist.
Returns
mixed
getConfigOrFail() ¶ public
getConfigOrFail(string $key): mixed
Returns the config for this specific key.
The config value for this key must exist, it can never be null.
Parameters
-
string
$key The key to get.
Returns
mixed
Throws
InvalidArgumentException
has() ¶ public
has(string $name): bool
Check whether a given object is loaded.
Parameters
-
string
$name The object name to check for.
Returns
bool
load() ¶ public
load(string $name, array<string, mixed> $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 $config['enabled'] = false
to exclude constructed objects from being registered for events.
Using {@link \Cake\Controller\Component::$components} 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
-
string
$name The name/class of the object to load.
-
array<string, mixed>
$config optional Additional settings to use when loading the object.
Returns
mixed
Throws
Exception
If the class cannot be found.
normalizeArray() ¶ public
normalizeArray(array $objects): array<string, array>
Normalizes an object array, creates an array that makes lazy loading easier
Parameters
-
array
$objects Array of child objects to normalize.
Returns
array<string, array>
reset() ¶ public
reset(): $this
Clear loaded instances in the registry.
If the registry subclass has an event manager, the objects will be detached from events as well.
Returns
$this
set() ¶ public
set(string $name, object $object): $this
Set an object directly into the registry by name.
If this collection implements events, the passed object will be attached into the event manager
Parameters
-
string
$name The name of the object to set in the registry.
-
object
$object instance to store in the registry
Returns
$this
setConfig() ¶ public
setConfig(array<string, mixed>|string $key, mixed|null $value = null, bool $merge = true): $this
Sets the config.
Usage
Setting a specific value:
$this->setConfig('key', $value);
Setting a nested value:
$this->setConfig('some.nested.key', $value);
Updating multiple config settings at the same time:
$this->setConfig(['one' => 'value', 'another' => 'value']);

-
array<string, mixed>|string
$key The key to set, or a complete array of configs.
-
mixed|null
$value optional The value to set.
-
bool

Parameters
-
