    • create

      public static KeeperException create(KeeperException.Code code, String path)
      All non-specific keeper exceptions should be constructed via this factory method in order to guarantee consistency in error codes and such. If you know the error code, then you should construct the special purpose exception directly. That will allow you to have the most specific possible declarations of what exceptions might actually be thrown.
      Parameters:
      code - The error code.
      path - The ZooKeeper path being operated on.
      Returns:
      The specialized exception, presumably to be thrown by the caller.

      public static KeeperException create(KeeperException.Code code)
      All non-specific keeper exceptions should be constructed via this factory method in order to guarantee consistency in error codes and such. If you know the error code, then you should construct the special purpose exception directly. That will allow you to have the most specific possible declarations of what exceptions might actually be thrown.
      Parameters:
      code - The error code of your new exception. This will also determine the specific type of the exception that is returned.
      Returns:
      The specialized exception, presumably to be thrown by the caller.

    • getResults

      public List<OpResult> getResults()

      Returns:
      A copy of the list of results from the operations in the multi-request.
