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

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

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.

Enum Constant Detail

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
