Attribute inheritance

All methods in this package use ReflectionAttribute::IS_INSTANCEOF by default. This means child attributes match when you query for a parent.

##Example

#[Attribute(Attribute::TARGET_CLASS)]
class CacheStrategy
{
    public function __construct(public int $ttl = 3600) {}
}

#[Attribute(Attribute::TARGET_CLASS)]
class AggressiveCache extends CacheStrategy
{
    public function __construct()
    {
        parent::__construct(ttl: 86400);
    }
}

#[AggressiveCache]
class ProductCatalog {}

Querying for the parent CacheStrategy will find the child AggressiveCache:

use Spatie\Attributes\Attributes;

$cache = Attributes::get(ProductCatalog::class, CacheStrategy::class);

$cache instanceof AggressiveCache; // true
$cache->ttl; // 86400

Querying for the exact child class works too:

$cache = Attributes::get(ProductCatalog::class, AggressiveCache::class);

$cache->ttl; // 86400

This applies to all methods: get(), has(), getAll(), onMethod(), onProperty(), onConstant(), onParameter(), getAllOnMethod(), getAllOnProperty(), getAllOnConstant(), getAllOnParameter(), onFunction(), and find().
