Class AbstractDoubleComparator

java.lang.Object

it.unimi.dsi.fastutil.doubles.AbstractDoubleComparator

All Implemented Interfaces:

DoubleComparator, Comparator<Double>

public abstract class AbstractDoubleComparator
extends Object
implements DoubleComparator

An abstract class facilitating the creation of type-specific comparators.

To create a type-specific comparator you need both a method comparing primitive types and a method comparing objects. However, if you have the first one you can just inherit from this class and get for free the second one.
