java.lang.Object

com.sap.engine.interfaces.messaging.api.DeliverySemantics

All Implemented Interfaces:

Serializable

public class DeliverySemantics
extends Object
implements Serializable

The DeliverySemantics class is a type-safe enumeration of delivery semantics of a message exchange and as such defines the quality of service.
Currently, the DeliverySemantics values defined by this class are:

• BestEffort Message delivery is not guaranteed.
• ExactlyOnce Message is guaranteed to be delivered exactly once.
• ExactlyOnceInOrder Message is guaranteed to be delivered exactly once and the sequence of the message delivery is maintained.

Code sample:

DeliverySemantics ds = DeliverySemantics.ExactlyOnce;
