Class NumOrTwoSeqOrNdArr

java.lang.Object

com.fa993.types.supertype.Either.OfThree<Double,double[],double[][]>

com.fa993.types.supertype.NumOrTwoSeqOrNdArr

public class NumOrTwoSeqOrNdArr
extends Either.OfThree<Double,double[],double[][]>

Represents a specialized version of Either.OfThree that can hold one of three types:

• A Double value
• An array of two double values
• A 2D array of double values

This class enforces specific constraints on the second type, requiring it to be a sequence of exactly two doubles.

Constructor Detail

NumOrTwoSeqOrNdArr

protected NumOrTwoSeqOrNdArr(Double first,
                             double[] second,
                             double[][] third,
                             Either.Selector selector)

Constructs a NumOrTwoSeqOrNdArr instance with the specified value and selector.

Parameters:

first - the Double value, or null if not selected

second - the array of two double values, or null if not selected

third - the 2D array of double values, or null if not selected

selector - the Either.Selector indicating the selected type

Method Detail

first

public static NumOrTwoSeqOrNdArr first(Double first)

Creates a NumOrTwoSeqOrNdArr instance with the Double value selected.

Parameters:

first - the Double value (must not be null)

Returns:

a NumOrTwoSeqOrNdArr instance with the Double value selected

Throws:

NullPointerException - if first is null

second

public static NumOrTwoSeqOrNdArr second(double[] second)

Creates a NumOrTwoSeqOrNdArr instance with the array of two double values selected.

Parameters:

second - the array of two double values (must not be null, and must have a length of 2)

Returns:

a NumOrTwoSeqOrNdArr instance with the array of two double values selected

Throws:

NullPointerException - if second is null

IllegalArgumentException - if second does not have a length of 2

third

public static NumOrTwoSeqOrNdArr third(double[][] third)

Creates a NumOrTwoSeqOrNdArr instance with the 2D array of double values selected.

Parameters:

third - the 2D array of double values (must not be null)

Returns:

a NumOrTwoSeqOrNdArr instance with the 2D array of double values selected

Throws:

NullPointerException - if third is null
