用于验证元素集合的DRY辅助工具。
具有类型提示属性,它们可以在没有设置器的情况下确保集合的类型安全。
class Foo { public StringCollection $bar; public function __construct() { $this->bar = new StringCollection(); } } $foo = new Foo(); $foo->bar[] = 123; // throws InvalidArgumentException
扩展以用于自己的实体
class BarEntity { public string $baz; } class BarCollection extends \PhF\Collection\Collection { protected static $invalidElementMessageAllowed = BarEntity::class; public function validate( $value ): bool { return $value instanceof BarEntity; } } class Foo { public BarCollection $bar; public function __construct() { $this->bar = new BarCollection(); } }
