Enum ProgressToken.BucketState

  • All Implemented Interfaces:
    Serializable, Comparable<ProgressToken.BucketState>
    Enclosing class:
    ProgressToken

    public static enum ProgressToken.BucketState
    extends Enum<ProgressToken.BucketState>
    Any bucket kept track of by a ProgressToken instance may be in one of two states: pending or active. Pending means that a bucket may be returned by a VisitorIterator, i.e. it is ready for visiting, while active means that a bucket is currently being visited and may thus not be returned from an iterator. Getting a pending bucket via the iterator sets its state to active and updating an active bucket sets its state back to pending again.

      • values

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

        public static ProgressToken.BucketState 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
