Enum NaNStrategy

java.lang.Object

java.lang.Enum<NaNStrategy>

fr.cnes.sirius.patrius.math.stat.ranking.NaNStrategy

All Implemented Interfaces:

Serializable, Comparable<NaNStrategy>

public enum NaNStrategy
extends Enum<NaNStrategy>

Strategies for handling NaN values in rank transformations.

• MINIMAL - NaNs are treated as minimal in the ordering, equivalent to (that is, tied with) Double.NEGATIVE_INFINITY.
• MAXIMAL - NaNs are treated as maximal in the ordering, equivalent to Double.POSITIVE_INFINITY
• REMOVED - NaNs are removed before the rank transform is applied
• FIXED - NaNs are left "in place," that is the rank transformation is applied to the other elements in the input array, but the NaN elements are returned unchanged.
• FAILED - If any NaN is encountered in the input array, an appropriate exception is thrown

Since:

2.0

Method Detail

values

public static NaNStrategy[] 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 (NaNStrategy c : NaNStrategy.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static NaNStrategy 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
