Enum Class AddWatchMode

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

public enum AddWatchMode extends Enum<AddWatchMode>
  • Enum Constant Details

    • PERSISTENT

      public static final AddWatchMode PERSISTENT

      Set a watcher on the given path that does not get removed when triggered (i.e. it stays active until it is removed). This watcher is triggered for both data and child events. To remove the watcher, use removeWatches() with WatcherType.Any. The watcher behaves as if you placed an exists() watch and a getData() watch on the ZNode at the given path.

    • PERSISTENT_RECURSIVE

      public static final AddWatchMode PERSISTENT_RECURSIVE

      Set a watcher on the given path that: a) does not get removed when triggered (i.e. it stays active until it is removed); b) applies not only to the registered path but all child paths recursively. This watcher is triggered for both data and child events. To remove the watcher, use removeWatches() with WatcherType.Any

      The watcher behaves as if you placed an exists() watch and a getData() watch on the ZNode at the given path and any ZNodes that are children of the given path including children added later.

      NOTE: when there are active recursive watches there is a small performance decrease as all segments of ZNode paths must be checked for watch triggering.

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

    • valueOf

      public static AddWatchMode valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name
      NullPointerException - if the argument is null
