## Enum SemiVariance.Direction

- java.lang.Object
- - java.lang.Enum<SemiVariance.Direction>
  - - org.apache.commons.math3.stat.descriptive.moment.SemiVariance.Direction

- All Implemented Interfaces:
    Serializable, Comparable<SemiVariance.Direction>
  Enclosing class:
    SemiVariance

      public static enum SemiVariance.Direction
      extends 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 Constant Summary

    Enum Constants
    Enum Constant and 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 Summary

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `static SemiVariance.Direction` | `valueOf(String name)` Returns the enum constant of this type with the specified name.
    `static SemiVariance.Direction[]` | `values()` Returns an array containing the constants of this enum type, in the order they are declared.

    - #### UPSIDE

          public static final SemiVariance.Direction UPSIDE

      The UPSIDE Direction is used to specify that the observations above the cutoff point will be used to calculate SemiVariance

    - #### DOWNSIDE

          public static final SemiVariance.Direction DOWNSIDE

      The DOWNSIDE Direction is used to specify that the observations below 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(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
