Enum Constant Details
-
PERSISTENT
The znode will not be automatically deleted upon client's disconnect. -
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
The znode will be deleted upon the client's disconnect. -
EPHEMERAL_SEQUENTIAL
The znode will be deleted upon the client's disconnect, and its name will be appended with a monotonically increasing number. -
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.NoNodeException
when creating children inside of this container node. -
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
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.
