Enum Constant Detail- 
PERSISTENTpublic static final CreateMode PERSISTENT The znode will not be automatically deleted upon client's disconnect.
 - 
PERSISTENT_SEQUENTIALpublic 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.
 - 
EPHEMERALpublic static final CreateMode EPHEMERAL The znode will be deleted upon the client's disconnect.
 - 
EPHEMERAL_SEQUENTIALpublic 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.
 - 
CONTAINERpublic 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 getKeeperException.NoNodeExceptionwhen creating children inside of this container node.
 - 
PERSISTENT_WITH_TTLpublic 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_TTLpublic 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.

Method Detail- 
valuespublic static CreateMode[] 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 (CreateMode c : CreateMode.values()) System.out.println(c); - Returns:
- an array containing the constants of this enum type, in the order they are declared
 
 - 
valueOfpublic 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
