Enum SemiVariance.Direction

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<SemiVariance.Direction>
    Enclosing class:
    SemiVariance
    public static enum SemiVariance.Direction
extends java.lang.Enum<SemiVariance.Direction>
    The direction of the semivariance - either upside or downside. The direction is represented by boolean, with true corresponding to UPSIDE semivariance.

      Enum Constants 
      Enum Constant Description
      DOWNSIDE
      The DOWNSIDE Direction is used to specify that the observations below the cutoff point will be used to calculate SemiVariance
      UPSIDE
      The UPSIDE Direction is used to specify that the observations above the cutoff point will be used to calculate SemiVariance

    • Method Detail

      • values

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

      • valueOf

        public static SemiVariance.Direction 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
