Tags
Return values
object —Object instance.
getIterator()
Returns an array iterator.
    public
                    getIterator() : Traversable
    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.
load()
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
loaded()
Get the list of loaded objects.
    public
                    loaded() : array<string|int, string>
    Return values
array<string|int, string> —List of object names.
normalizeArray()
Normalizes an object array, creates an array that makes lazy loading easier
    public
                    normalizeArray(array<string|int, mixed> $objects) : array<string, array<string|int, mixed>>
    Parameters
- $objects : array<string|int, mixed>
 - 
                    
Array of child objects to normalize.
 
Return values
array<string, array<string|int, mixed>> —Array of normalized objects.
reset()
Clear loaded instances in the registry.
    public
                    reset() : $this
    If the registry subclass has an event manager, the objects will be detached from events as well.
Return values
$thisset()
Set an object directly into the registry by name.
    public
                    set(string $name, object $object) : $this
    If this collection implements events, the passed object will be attached into the event manager
Parameters
- $name : string
 - 
                    
The name of the object to set in the registry.
 - $object : object
 - 
                    
instance to store in the registry
 
Tags
Return values
$thisunload()
Remove a single adapter from the registry.
    public
                    unload(string $name) : $this
    Parameters
- $name : string
 - 
                    
The adapter name.
 
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.
