Class JArrays.DoubleArrayComparator

java.lang.Object
net.algart.arrays.JArrays.DoubleArrayComparator
All Implemented Interfaces:
ArrayComparator, ArrayComparator32
Enclosing class:
JArrays
public static class JArrays.DoubleArrayComparator extends Object implements ArrayComparator32
Simple implementation of ArrayComparator, comparing elements of double[] array.

Note that elements of double[] array are compared by Double.compare(double, double) method. So, NaN is considered to be equal to itself and greater than all other double alues (including POSITIVE_INFINITY), and 0.0 is considered be greater than -0.0.
