Configuration

The framework's central configuration/DI container: a nested array of settings and lazily-instantiated objects (unserialize's '$' => ClassName convention), addressable by path (get/walk) and mergeable from multiple sources (load).

createInstance($class, $args)

Configuration.php:153

Create a new instance using default arguments stored in the configuration: 1. If a configuration is set at the classname (if instantiating class `MyClass`, it will look for a configuration set at `MyClass`), it is injected in the current given arguments.

function createInstance(string $class, array $args = []): object

2. If the arguments has the key `$`, the instance is created by unserializing the arguments (WARNING: constructor won't be called) Else, the arguments are unserialized and then the class constructor is called with these arguments. ## Using the key `$` NOTE: be careful, when using the `$` configuration, the constructor is not called, as the process become an unserialization. - You can change the classname to instantiate: - You can set a factory to create the class:

$class	string	the classname to instantiate or a valid path in the config. If it is a path, there MUST be the key '$' in the configuration to indicate which class to instantiate.
$args = []	array
returns	object
throws		if the configuration is invalid or no class is defined
throws		if the class does not exist
throws		if an instance is already present at the path and cannot be injected

with the configuration [MyClass:class => ['$' => MyOtherClass::class]], createInstance(MyClass:class) => MyOtherClass{}

function createMyClass(...$args) {return new MyOtherClass(...$args);} with the configuration [MyClass:class => ['$' => 'createMyClass']],

freeInstance($class, $config)

Configuration.php:204

Release an already-unserialized instance stored at $class's own key (the following get/getInstance call re-creates it).

function freeInstance(string $class, ?array $config = null): bool

$class	string
$config = null	null \| array	if given, replaces the stored config entry with this (a fresh instance will be built from it next); if null, the key is removed entirely (falls back to whatever `load` put there, if anything).
returns	bool	false if $class had no instance stored there (nothing to free).

get($id, $default)

Configuration.php:102

function get($id, mixed $default = null): mixed

$id		a `/`-separated path into the configuration tree.
$default = null	mixed	returned if $id doesn't exist -- only if actually passed (checked via `func_num_args()`, so passing `null` explicitly still suppresses the exception); if omitted, a missing $id throws instead.
returns	mixed	the value at $id -- if it (or an ancestor along the path) is a serialized object descriptor (`isSerialized`), it's lazily unserialized into a real object (and cached in place) the first time it's reached.
throws		if $id doesn't exist and $default wasn't passed.

Configuration::Shared()->get('MyClass/missing', 'fallback'); // 'fallback', no exception

getInstance($class)

Configuration.php:187

Unserialize an instance stored in the configuration.

function getInstance(string $class): object

Similar to get, but if no configuration is found, it will create an instance of this class anyway (get will throw an exception) and store it at its classname.

$class	string
returns	object

hasInstance($class)

Configuration.php:214

function hasInstance(string $class): bool

$class	string
returns	bool	whether $class's own key currently holds an already-unserialized object (vs. raw config, or nothing).

IsShared()

staticConfiguration.php:40

static function IsShared(): bool

returns

bool

whether the shared instance has been created yet.

load($configs)

Configuration.php:51

Merge one or more configurations into the current one (inject), in order -- each $configs argument is either an already-decoded array, or a path to a .php file (returning an array) or .json file to load one from.

function load(array|string ...$configs): void

...$configs	array \| string
returns	void
throws		if a string config's extension isn't `.php`/`.json`, or a `.php` config doesn't return an array.

onCreate($event)

Configuration.php:240

#[MMO\core\attributes\Listen('MMO\\core\\events\\Create', order: 100)] function onCreate(MMO\core\events\Create $event): void

See: Create event handler: fulfills any not-yet-handled Create event via createInstance.

$event	Create
returns	void

Shared()

staticConfiguration.php:27

static function Shared(): static

returns

static

the shared instance, creating it on first access.

Unshare()

staticConfiguration.php:35

Remove the shared instance

static function Unshare(): void

returns

void

__construct()

Configuration.php:21

Registers this instance for Create event dispatch (onCreate) via connect.

function __construct()

`push($id, $value, $create)`	Container	Push a value in content
`set($id, $value, $create)`	Container	Set a value at $id, creating intermediate structure as needed.
`setContent($content)`	Container	Replace the whole content wholesale.
`setId($id)`	Container
`toArray()`	Container	Convert the content to a plain array, recursively converting any nested `iArray` value (e.g.
`UnFetch($url)`	Container	Forget the container registered under $url (it can be `Fetch-ed` again afterward, rebuilding it).
