Componenta Reflection
=====================

[](#componenta-reflection)

Small reflection helper for Componenta internals.

Installation
------------

[](#installation)

```
composer require componenta/reflection
```

Requirements
------------

[](#requirements)

- PHP 8.4+

Related Packages
----------------

[](#related-packages)

This package is standalone and is mostly an internal helper for Componenta libraries.

PackageWhy it uses reflection`componenta/di`Reads parameters, properties, and attributes during dependency resolution.`componenta/interceptor`Reads method attributes for attribute-based interceptors.`componenta/class-finder`Attribute and inheritance filters can inspect discovered classes.`componenta/policy`Attribute policies can be read through reflection providers or app compilation.What It Provides
----------------

[](#what-it-provides)

- Cached reflection for classes, objects, closures, functions, methods, and invokable objects.
- Attribute lookup helpers for a single reflector.
- Deep attribute lookup across a class, its methods, properties, and constants.
- `WeakMap`-backed metadata cache for attribute instances.

Reflecting Values
-----------------

[](#reflecting-values)

```
use Componenta\Reflection\Reflection;

$class = Reflection::class(App\Service\UserService::class);
$object = Reflection::object($service);
$closure = Reflection::callable(static fn(): string => 'ok');
$method = Reflection::callable([App\Service\UserService::class, 'handle']);
```

`Reflection::reflect()` accepts mixed input and returns the matching PHP reflector or `null`.

```
$reflector = Reflection::reflect($value);
```

Reading Attributes
------------------

[](#reading-attributes)

```
use Componenta\Reflection\Reflection;

$class = Reflection::class(App\Command\CreatePostCommand::class);

$policies = Reflection::getMetadata($class, PermissionPolicy::class);
$policy = Reflection::getFirstMetadata($class, PermissionPolicy::class);
$hasPolicy = Reflection::hasMetadata($class, PermissionPolicy::class);
```

`getMetadata()` returns `array|null`: `null` means no matching attributes.

Deep Attribute Lookup
---------------------

[](#deep-attribute-lookup)

```
$attributes = Reflection::getDeepMetadata($class, SomeAttribute::class);

foreach ($attributes as $path => $items) {
    // $path examples:
    // App\Command\CreatePostCommand
    // App\Command\CreatePostCommand::handle
    // App\Command\CreatePostCommand::$title
    // App\Command\CreatePostCommand::STATUS
}
```

Cache Management
----------------

[](#cache-management)

```
Reflection::clearReflectors();
```

Use this in tests when a test mutates reflector state or needs isolation.
