Enum CreateMode

java.lang.Object
java.lang.Enum<CreateMode>
org.apache.zookeeper.CreateMode
All Implemented Interfaces:
Serializable, Comparable<CreateMode>

@Public public enum CreateMode extends Enum<CreateMode>
CreateMode value determines how the znode is created on ZooKeeper.
  • Enum Constant Details

    • PERSISTENT

      public static final CreateMode PERSISTENT
      The znode will not be automatically deleted upon client's disconnect.
    • PERSISTENT_SEQUENTIAL

      public static final CreateMode PERSISTENT_SEQUENTIAL
      The znode will not be automatically deleted upon client's disconnect, and its name will be appended with a monotonically increasing number.
    • EPHEMERAL

      public static final CreateMode EPHEMERAL
      The znode will be deleted upon the client's disconnect.
    • EPHEMERAL_SEQUENTIAL

      public static final CreateMode EPHEMERAL_SEQUENTIAL
      The znode will be deleted upon the client's disconnect, and its name will be appended with a monotonically increasing number.
    • CONTAINER

      public static final CreateMode CONTAINER
      The znode will be a container node. Container nodes are special purpose nodes useful for recipes such as leader, lock, etc. When the last child of a container is deleted, the container becomes a candidate to be deleted by the server at some point in the future. Given this property, you should be prepared to get KeeperException.NoNodeException when creating children inside of this container node.
    • PERSISTENT_WITH_TTL

      public static final CreateMode PERSISTENT_WITH_TTL
      The znode will not be automatically deleted upon client's disconnect. However if the znode has not been modified within the given TTL, it will be deleted once it has no children.
    • PERSISTENT_SEQUENTIAL_WITH_TTL

      public static final CreateMode PERSISTENT_SEQUENTIAL_WITH_TTL
      The znode will not be automatically deleted upon client's disconnect, and its name will be appended with a monotonically increasing number. However if the znode has not been modified within the given TTL, it will be deleted once it has no children.

    • values

      public static CreateMode[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared
    • valueOf

      public static CreateMode 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
