Enum Order

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<Order>
    public enum Order
extends java.lang.Enum<Order>
    Used to describe or modify the lexicographical sort order of a byte[]. Default ordering is considered ASCENDING. The order of a byte[] can be inverted, resulting in DESCENDING order, by replacing each byte with its 1's compliment.

      • values

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

      • valueOf

        public static Order 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

      • cmp

        public abstract int cmp​(int cmp)
        Returns the adjusted trichotomous value according to the ordering imposed by this Order.

      • apply

        public abstract byte apply​(byte val)
        Apply order to the byte val.

      • apply

        public abstract void apply​(byte[] val)
        Apply order to the byte array val.

      • apply

        public abstract void apply​(byte[] val,
                           int offset,
                           int length)
        Apply order to a range within the byte array val.
