  • Enum Constant Details

    • REQUESTED

      public static final Topics.UnsubscribeReason REQUESTED
      Unsubscribed by the subscribing session.

    • CONTROL

      public static final Topics.UnsubscribeReason CONTROL
      The unsubscription was requested either by another session or by the server.

    • REMOVAL

      public static final Topics.UnsubscribeReason REMOVAL
      The unsubscription occurred because the topic was removed.

    • AUTHORIZATION

      public static final Topics.UnsubscribeReason AUTHORIZATION
      The unsubscription occurred because the session is no longer authorized to access the topic.
      Since:
      5.9

    • SUBSCRIPTION_REFRESH

      public static final Topics.UnsubscribeReason SUBSCRIPTION_REFRESH
      The server has re-subscribed this session to the topic. Existing streams are unsubscribed because the topic type and other attributes may have changed.

      This can happen if a set of servers is configured to use session replication, and a session connected to one server reconnects ( "fails over") to a different server.

      Since:
      5.9

    • STREAM_CHANGE

      public static final Topics.UnsubscribeReason STREAM_CHANGE
      A fallback stream has been unsubscribed due to the addition of a stream that selects the topic.
      Since:
      5.9

    • BACK_PRESSURE

      public static final Topics.UnsubscribeReason BACK_PRESSURE
      The server has a significant backlog of messages for the session, and the topic specification has the conflation topic property set to "unsubscribe". The session can resubscribe to the topic. The unsubscription is not persisted to the cluster. If the session fails over to a different server it will be resubscribed to the topic.

    • BRANCH_MAPPINGS

      public static final Topics.UnsubscribeReason BRANCH_MAPPINGS
      The unsubscription occurred because branch mapping rules changed.
      Since:
      6.7

    • UNKNOWN_UNSUBSCRIBE_REASON

      public static final Topics.UnsubscribeReason UNKNOWN_UNSUBSCRIBE_REASON
      A reason that is unsupported by the session.
