Enumeration of states the ZooKeeper may be at the event


Enum Constant Summary
AuthFailed
          Auth failed state
ConnectedReadOnly
          The client is connected to a read-only server, that is the server which is not currently connected to the majority.
Disconnected
          The client is in the disconnected state - it is not connected to any server in the ensemble.
Expired
          The serving cluster has expired this session.
NoSyncConnected
          Deprecated. 
SaslAuthenticated
          SaslAuthenticated: used to notify clients that they are SASL-authenticated, so that they can perform Zookeeper actions with their SASL-authorized permissions.
SyncConnected
          The client is in the connected state - it is connected to a server in the ensemble (one of the servers specified in the host connection parameter during ZooKeeper client creation).
Unknown
          Deprecated.

Enum Constant Detail

Unknown

@Deprecated
public static final Watcher.Event.KeeperState Unknown
Deprecated. 
Unused, this state is never generated by the server


Disconnected

public static final Watcher.Event.KeeperState Disconnected
The client is in the disconnected state - it is not connected to any server in the ensemble.


NoSyncConnected

@Deprecated
public static final Watcher.Event.KeeperState NoSyncConnected
Deprecated. 
Unused, this state is never generated by the server


SyncConnected

public static final Watcher.Event.KeeperState SyncConnected
The client is in the connected state - it is connected to a server in the ensemble (one of the servers specified in the host connection parameter during ZooKeeper client creation).


AuthFailed

public static final Watcher.Event.KeeperState AuthFailed
Auth failed state


ConnectedReadOnly

public static final Watcher.Event.KeeperState ConnectedReadOnly
The client is connected to a read-only server, that is the server which is not currently connected to the majority. The only operations allowed after receiving this state is read operations. This state is generated for read-only clients only since read/write clients aren't allowed to connect to r/o servers.


SaslAuthenticated

public static final Watcher.Event.KeeperState SaslAuthenticated
SaslAuthenticated: used to notify clients that they are SASL-authenticated, so that they can perform Zookeeper actions with their SASL-authorized permissions.


Expired

public static final Watcher.Event.KeeperState Expired
The serving cluster has expired this session. The ZooKeeper client connection (the session) is no longer valid. You must create a new client connection (instantiate a new ZooKeeper instance) if you with to access the ensemble.

Method Detail

values

public static Watcher.Event.KeeperState[] 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 (Watcher.Event.KeeperState c : Watcher.Event.KeeperState.values())
    System.out.println(c);

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

valueOf

public static Watcher.Event.KeeperState 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

getIntValue

public int getIntValue()

fromInt

public static Watcher.Event.KeeperState fromInt(int intValue)
