Enum Class DuplicateDetectionPolicy

java.lang.Object

java.lang.Enum<DuplicateDetectionPolicy>

org.j7m.middleware.api.reliability.DuplicateDetectionPolicy

All Implemented Interfaces:

Serializable, Comparable<DuplicateDetectionPolicy>, Constable

public enum DuplicateDetectionPolicy
extends Enum<DuplicateDetectionPolicy>

Duplicate handling policy for a dedupe key.

The enum is immutable and thread-safe. Durable duplicate detection is a later phase; Phase 6.1 defines the policy contract and a non-durable test implementation.
