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.

_configDelete() ¶ protected

_configDelete(string $key): void

Deletes a single config key.

Parameters

string $key: Key to delete.

Returns

void

Throws

Cake\Core\Exception\CakeException
if attempting to clobber existing config

_configRead(string|null $key): mixed

Reads a config key.

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.

Returns

void

Throws

Cake\Core\Exception\CakeException
if attempting to clobber existing config

_create() ¶ protected

_create(object|string $class, string $alias, array<string, mixed> $config): Authentication\Identifier\IdentifierInterface

Creates identifier instance.

This method should construct and do any other initialization logic required.

Parameters

object|string $class: Identifier class.
string $alias: Identifier alias.
array<string, mixed> $config: Config array.

Returns

Authentication\Identifier\IdentifierInterface

Throws

RuntimeException

_resolveClassName() ¶ protected

_resolveClassName(string $class): string|null

Resolves identifier class name.

Parameters

string $class: Class name to be resolved.

Returns

string|null

_throwMissingClassError() ¶ protected

_throwMissingClassError(string $class, string|null $plugin): void

Throw an exception when the requested object name is missing.

Parameters

string $class: Missing class.
string|null $plugin: Class plugin.

Returns

void

Throws

RuntimeException

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

count() ¶ public

count(): int

Returns the number of loaded objects.

Returns

int

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');

mixed $default optional: The return value when the key does not exist.

Returns

mixed

getConfigOrFail() ¶ public

isEmpty() ¶ public

isEmpty(): bool

Returns true if a collection is empty.

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.

loaded() ¶ public

loaded(): array<string>

Get the list of loaded objects.

Returns

array<string>

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']);

Parameters

array<string, mixed>|string $key: The key to set, or a complete array of configs.
mixed|null $value optional: The value to set.
bool $merge optional: Whether to recursively merge or overwrite existing config, defaults to true.

Returns

$this

Throws

Cake\Core\Exception\CakeException
When trying to set a key that is invalid.

unload() ¶ public

unload(string $name): $this

Remove an object from the registry.

If this registry has an event manager, the object will be detached from any events as well.

Parameters

string $name: The name of the object to remove from the registry.
