Interface StatelessCallabackComponent<L,A,M>

Type Parameters:

L - defines the message listener type

A - defines the basic event type

M - defines the basic message type

All Superinterfaces:

java.lang.Comparable<ComponentBase<L,M>>, ComponentBase<L,M>, SubComponent<L,A,M>

public interface StatelessCallabackComponent<L,A,M>
extends SubComponent<L,A,M>

Represents a state less background/callback component. This component has a typical handle method, the return value is typically a non UI value (but it can be). Every message to this component should be handled in a separate thread and component instance, managed by an executor (to avoid garbage). Do not use private members as it is not guaranteed that that you contact the same instance twice. This component type is good for scaling tasks like performing operations on many folders or tables in database. The return value will be send to message caller or to specified handleTargetId.
