ArrayOf
extends ObjAttribute
in package
Attribute specifying the element type of an array property.
Array-typed properties on Obj have no inherent element type, so #[ArrayOf] tells __unserialize() what class to instantiate (and call parse() on) for each element of the incoming array.
Usage:
class Order extends Obj {
#[ArrayOf(LineItem::class)]
public array $items;
}
