Registry for Helpers. Provides features for lazily loading helpers.
Debug friendly object properties.
Provide public read access to the loaded objects
Provide isset access to _loaded
Sets an object.
Unsets an object.
Check for duplicate object loading.
Create the helper instance.
Resolve a helper classname.
Throws an exception when a helper is missing.
Returns the number of loaded objects.
Get loaded object instance.
Returns an array iterator.
Check whether a given object is loaded.
Loads/constructs an object instance.
Get the list of loaded objects.
Normalizes an object array, creates an array that makes lazy loading easier
Clear loaded instances in the registry.
Set an object directly into the registry by name.
Sets The IO instance that should be passed to the shell helpers
Remove an object from the registry.
__debugInfo(): array<string, mixed>
Debug friendly object properties.
array<string, mixed>
__get(string $name): object|null
Provide public read access to the loaded objects
string
$name Name of property to read
object|null
__isset(string $name): bool
Provide isset access to _loaded
string
$name Name of object being checked.
bool
__set(string $name, object $object): void
Sets an object.
string
$name Name of a property to set.
object
$object Object to set.
void
__unset(string $name): void
Unsets an object.
string
$name Name of a property to unset.
void
_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.
string
$name The name of the alias in the registry.
array<string, mixed>
$config The config data for the new instance.
void
RuntimeException
_create(object|string $class, string $alias, array<string, mixed> $config): Cake\Console\Helper
Create the helper instance.
Part of the template method for Cake\Core\ObjectRegistry::load()
object|string
$class The classname to create.
string
$alias The alias of the helper.
array<string, mixed>
$config An array of settings to use for the helper.
Cake\Console\Helper
_resolveClassName(string $class): string|null
Resolve a helper classname.
Will prefer helpers defined in Command\Helper over those defined in Shell\Helper.
Part of the template method for {@link \Cake\Core\ObjectRegistry::load()}.
string
$class Partial classname to resolve.
string|null
_throwMissingClassError(string $class, string|null $plugin): void
Throws an exception when a helper is missing.
Part of the template method for Cake\Core\ObjectRegistry::load() and Cake\Core\ObjectRegistry::unload()
string
$class The classname that is missing.
string|null
$plugin The plugin the helper is missing in.
void
Cake\Console\Exception\MissingHelperException
count(): int
Returns the number of loaded objects.
int
get(string $name): object
Get loaded object instance.
string
$name Name of object.
object
RuntimeException
getIterator(): Traversable
Returns an array iterator.
Traversable
has(string $name): bool
Check whether a given object is loaded.
string
$name The object name to check for.
bool
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.
string
$name The name/class of the object to load.
array<string, mixed>
$config optional Additional settings to use when loading the object.
mixed
Exception
loaded(): array<string>
Get the list of loaded objects.
array<string>
normalizeArray(array $objects): array<string, array>
Normalizes an object array, creates an array that makes lazy loading easier
array
$objects Array of child objects to normalize.
array<string, array>
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.
$this
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
string
$name The name of the object to set in the registry.
object
$object instance to store in the registry
$this
setIo(Cake\Console\ConsoleIo $io): void
Sets The IO instance that should be passed to the shell helpers
Cake\Console\ConsoleIo
$io An io instance.
void
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.
string
$name The name of the object to remove from the registry.
$this
Shell to use to set params to tasks.
Cake\Console\ConsoleIo
Map of loaded objects.
