Method Detail
_create() protected ¶
_create( string|Psr\Log\LoggerInterface $class , string $alias , array $settings )
Create the logger instance.
Part of the template method for Cake\Core\ObjectRegistry::load()
Parameters
- string|Psr\Log\LoggerInterface $class
- The classname or object to make.
- string $alias
- The alias of the object.
- array $settings
- An array of settings to use for the logger.
Returns
The constructed logger class.
Throws
when an object doesn't implement the correct interface.
_resolveClassName() protected ¶
_resolveClassName( string $class )
Resolve a logger classname.
Part of the template method for Cake\Core\ObjectRegistry::load()
Parameters
- string $class
- Partial classname to resolve.
Returns
Either the correct classname or false.
_throwMissingClassError() protected ¶
_throwMissingClassError( string $class , string $plugin )
Throws an exception when a logger is missing.
Part of the template method for Cake\Core\ObjectRegistry::load()
Parameters
- string $class
- The classname that is missing.
- string $plugin
- The plugin the logger is missing in.
Throws
Methods inherited from Cake\Core\ObjectRegistry
__get() public ¶
__get( string $name )
Provide public read access to the loaded objects
Parameters
- string $name
- Name of property to read
Returns
__isset() public ¶
__isset( string $name )
Provide isset access to _loaded
Parameters
- string $name
- Name of object being checked.
Returns
__set() public ¶
__set( string $name , mixed $object )
Sets an object.
Parameters
- string $name
- Name of a property to set.
- mixed $object
- Object to set.
__unset() public ¶
__unset( string $name )
Unsets an object.
Parameters
- string $name
- Name of a property to unset.
_checkDuplicate() protected ¶
_checkDuplicate( string $name , array $config )
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 $config
- The config data for the new instance.
Throws
When a duplicate is found.
count() public ¶
count( )
Returns the number of loaded objects.
Returns
Implementation of
Countable::count()get() public ¶
get( string $name )
Get loaded object instance.
Parameters
- string $name
- Name of object.
Returns
Object instance if loaded else null.
getIterator() public ¶
getIterator( )
Returns an array iterator.
Returns
Implementation of
IteratorAggregate::getIterator()has() public ¶
has( string $name )
Check whether or not a given object is loaded.
Parameters
- string $name
- The object name to check for.
Returns
True is object is loaded else false.
load() public ¶
load( string $objectName , array $config [] )
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 $config['enabled'] = false
to exclude constructed objects from being registered for events.
Using Cake\Controller\Controller::$components as an example. You can alias an object by setting the 'className' key, i.e.,
public $components = [ 'Email' => [ 'className' => '\App\Controller\Component\AliasedEmailComponent' ]; ];
All calls to the Email component would use AliasedEmail instead.
Parameters
- string $objectName
- The name/class of the object to load.
- array $config optional []
- Additional settings to use when loading the object.
Returns
Throws
If the class cannot be found.
normalizeArray() public ¶
normalizeArray( array $objects )
Normalizes an object array, creates an array that makes lazy loading easier
Parameters
- array $objects
- Array of child objects to normalize.
Returns
Array of normalized objects.
reset() public ¶
reset( )
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 $objectName , object $object )
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 $objectName
- The name of the object to set in the registry.
- object $object
- instance to store in the registry
Returns
$this
