    • Enum Constant Detail

      • SYSTEMERROR

        public static final KeeperException.Code SYSTEMERROR
        System and server-side errors. This is never thrown by the server, it shouldn't be used other than to indicate a range. Specifically error codes greater than this value, but lesser than APIERROR, are system errors.

      • RUNTIMEINCONSISTENCY

        public static final KeeperException.Code RUNTIMEINCONSISTENCY
        A runtime inconsistency was found

      • DATAINCONSISTENCY

        public static final KeeperException.Code DATAINCONSISTENCY
        A data inconsistency was found

      • CONNECTIONLOSS

        public static final KeeperException.Code CONNECTIONLOSS
        Connection to the server has been lost

      • MARSHALLINGERROR

        public static final KeeperException.Code MARSHALLINGERROR
        Error while marshalling or unmarshalling data

      • NEWCONFIGNOQUORUM

        public static final KeeperException.Code NEWCONFIGNOQUORUM
        No quorum of new config is connected and up-to-date with the leader of last commmitted config - try invoking reconfiguration after new servers are connected and synced

      • RECONFIGINPROGRESS

        public static final KeeperException.Code RECONFIGINPROGRESS
        Another reconfiguration is in progress -- concurrent reconfigs not supported (yet)

      • UNKNOWNSESSION

        public static final KeeperException.Code UNKNOWNSESSION
        Unknown session (internal server use only)

      • APIERROR

        public static final KeeperException.Code APIERROR
        API errors. This is never thrown by the server, it shouldn't be used other than to indicate a range. Specifically error codes greater than this value are API errors (while values less than this indicate a SYSTEMERROR).

      • BADVERSION

        public static final KeeperException.Code BADVERSION
        Version conflict In case of reconfiguration: reconfig requested from config version X but last seen config has a different version Y

      • NOCHILDRENFOREPHEMERALS

        public static final KeeperException.Code NOCHILDRENFOREPHEMERALS
        Ephemeral nodes may not have children

      • SESSIONEXPIRED

        public static final KeeperException.Code SESSIONEXPIRED

        Invalid callback specified

      • SESSIONMOVED

        public static final KeeperException.Code SESSIONMOVED
        Session moved to another server, so operation is ignored

        public static final KeeperException.Code REQUESTTIMEOUT
        Request not completed within max allowed time.

      • RECONFIGDISABLED

        public static final KeeperException.Code RECONFIGDISABLED
        Attempts to perform a reconfiguration operation when reconfiguration feature is disabled.

      • SESSIONCLOSEDREQUIRESASLAUTH

        public static final KeeperException.Code SESSIONCLOSEDREQUIRESASLAUTH

        public static KeeperException.Code[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (KeeperException.Code c : KeeperException.Code.values())
    System.out.println(c);
        Returns:

      • valueOf

        public static KeeperException.Code valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
