Enum Class DeliveryMode

java.lang.Object
java.lang.Enum<DeliveryMode>
org.j7m.middleware.api.reliability.DeliveryMode
All Implemented Interfaces:
Serializable, Comparable<DeliveryMode>, Constable
public enum DeliveryMode extends Enum<DeliveryMode>
Transport-neutral delivery mode requested for one invocation.

The enum is immutable and thread-safe. It describes middleware retry and duplicate-handling semantics only; it does not claim business side-effect consistency.

  • Enum Constant Details

    • AT_MOST_ONCE_BEST_EFFORT

      public static final DeliveryMode AT_MOST_ONCE_BEST_EFFORT
      Send once and report the observed outcome without middleware retry.

    • AT_LEAST_ONCE_RETRYABLE

      public static final DeliveryMode AT_LEAST_ONCE_RETRYABLE
      Retry may be attempted only when the operation is retry-safe.

    • EFFECTIVELY_ONCE_PATTERN

      public static final DeliveryMode EFFECTIVELY_ONCE_PATTERN
      Effectively-once pattern metadata is present, but applications own side effects.

    • UNSUPPORTED_EXACTLY_ONCE

      public static final DeliveryMode UNSUPPORTED_EXACTLY_ONCE
      Generic exactly-once distributed execution was requested and is unsupported.
