ManagedScheduledExecutorService Arayüzü

Giriş
Şu satırı dahil ederiz

import javax.enterprise.concurrent.ManagedScheduledExecutorService;

ScheduledExecutorService gibidir ve EJB Timer'larına göre daha hafiftir. Açıklaması şöyle

it does not support features like transaction support, full lifecycle operations (create, read, cancel timers), which are supported by EJB Timers. In addition, EJB Timers can be persisted and so survive server crash and restart.
