ServiceCallback

ServiceCallback constraint and ServiceCallbackValidator enables to validate a value using a method of a service registered in Symfony's service container.

/**
 * @ServiceCallback(service="mydomain.specification.email_limit",method="isSatisfiedBy",
    message="email limit error.", errorPath="emailMax", groups={"user_check"})
 */
class User
{

/**
 * @DI\Service("mydomain.specification.email_limit")
 */
class EmailLimit
{
    public function isSatisfiedBy($target)
    {
        return $target->getEmailsCount() > 5;  // Sometimes exceed the limit.
    }
}

Return value and validation result

• When the service method returns false, the validation fails.
• When any other, the validation passes.
