Strategy

The strategy is an object of a class implementing StrategyInterface. It has only one method - apply which applies it. You can add conditions to it by applying PreCondition attribute and specify the condition under what this strategy may be applied. After all preconditions are met, the strategy is applied. You can manipulate it by specifying middlewares BeforeApply, AfterApply and OverApply, which, as you can guess, are applied before, after or have full control around the apply method.


#[PreCondition(RequiresEntityId::class)]
#[PreCondition(HasChanged::class, ['status'])]
#[BeforeApply(SaveEntity::class)]
class ShipOrder implements StrategyInterface
{
    public function apply(Entity $order) 
    {
        event(new OrderShipped($order));
    }
}
