Enum KeeperException.Code

java.lang.Object
  extended by java.lang.Enum<KeeperException.Code>
      extended by org.apache.zookeeper.KeeperException.Code
All Implemented Interfaces:
Serializable, Comparable<KeeperException.Code>, KeeperException.CodeDeprecated
Enclosing class:
KeeperException

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 Detail

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


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


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


INVALIDCALLBACK

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


NOTREADONLY

public static final KeeperException.Code NOTREADONLY
State-changing request is passed to read-only server

Method Detail

values

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:
an array containing the constants of this enum type, in the order they are declared

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.
Returns:
the enum constant with the specified name
Throws:
IllegalArgumentException - if this enum type has no constant with the specified name
NullPointerException - if the argument is null

intValue

public int intValue()
Get the int value for a particular Code.

Returns:
error code as integer

get

public static KeeperException.Code get(int code)
Get the Code value for a particular integer error code

Parameters:
code - int error code
Returns:
Code value corresponding to specified int code, or null
