Enum Class Order

java.lang.Object
java.lang.Enum<Order>
org.apache.hadoop.hbase.util.Order
All Implemented Interfaces:
Serializable, Comparable<Order>, Constable

@Public public enum Order extends 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.

    abstract void
    apply(byte[] val, int offset, int length)
    Apply order to a range within the byte array val.
    abstract int
    cmp(int cmp)
    Returns the adjusted trichotomous value according to the ordering imposed by this Order.
    static Order

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

      public static Order 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.)

      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      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.
