      • PLANNED

        public static final FragmentState PLANNED
        Fragment is planned but has not been scheduled yet. A Fragment will be in the planned state until, the dependencies of the Fragment have begun producing output.

      • SCHEDULING

        public static final FragmentState SCHEDULING
        Fragment instances are being scheduled on nodes.

      • RUNNING

        public static final FragmentState RUNNING
        Fragment is running.

      • PENDING

        public static final FragmentState PENDING
        Fragment has finished executing existing tasks but more instances could be scheduled in the future.

      • FINISHED

        public static final FragmentState FINISHED
        Fragment has finished executing and all output has been consumed.

      • ABORTED

        public static final FragmentState ABORTED
        Fragment was aborted due to a failure in the query. The failure was not in this Fragment.

      • FAILED

    • Method Detail

      • values

        public static FragmentState[] 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 (FragmentState c : FragmentState.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static FragmentState valueOf​(java.lang.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:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
