All Implemented Interfaces:
Serializable, Comparable<KeeperException.Code>, KeeperException.CodeDeprecated
Enclosing class:
KeeperException

@Public public static enum KeeperException.Code extends Enum<KeeperException.Code> implements KeeperException.CodeDeprecated
Codes which represent the various KeeperException types. This enum replaces the deprecated earlier static final int constants. The old, deprecated, values are in "camel case" while the new enum values are in all CAPS.
  • Enum Constant Details

    • OK

      public static final KeeperException.Code OK
      Everything is OK
    • 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
    • UNIMPLEMENTED

      public static final KeeperException.Code UNIMPLEMENTED
      Operation is unimplemented
    • OPERATIONTIMEOUT

      public static final KeeperException.Code OPERATIONTIMEOUT
      Operation timeout
    • BADARGUMENTS

      public static final KeeperException.Code BADARGUMENTS
      Invalid arguments
    • NEWCONFIGNOQUORUM

      public static final KeeperException.Code NEWCONFIGNOQUORUM
      No quorum of new config is connected and up-to-date with the leader of last committed 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).
    • NONODE

      public static final KeeperException.Code NONODE
      Node does not exist
    • NOAUTH

      public static final KeeperException.Code NOAUTH
      Not authenticated
    • 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
    • NODEEXISTS

      public static final KeeperException.Code NODEEXISTS
      The node already exists
    • NOTEMPTY

      public static final KeeperException.Code NOTEMPTY
      The node has children
    • SESSIONEXPIRED

      public static final KeeperException.Code SESSIONEXPIRED
      The session has been expired by the server

      Invalid callback specified
    • INVALIDACL

      public static final KeeperException.Code INVALIDACL
      Invalid ACL specified
    • AUTHFAILED

      public static final KeeperException.Code AUTHFAILED
      Client authentication failed
    • SESSIONMOVED

      public static final KeeperException.Code SESSIONMOVED

    • SESSIONCLOSEDREQUIRESASLAUTH

      public static final KeeperException.Code SESSIONCLOSEDREQUIRESASLAUTH
      The session has been closed by server because server requires client to do authentication with configured authentication scheme at the server, but client is not configured with required authentication scheme or configured but authentication failed (i.e. wrong credential used.).

      public static final KeeperException.Code QUOTAEXCEEDED
      Exceeded the quota that was set on the path.
    • THROTTLEDOP
