Interface CharComparator

All Superinterfaces:

java.util.Comparator<java.lang.Character>

All Known Implementing Classes:

CharComparators.NaturalImplicitComparator, CharComparators.OppositeComparator, CharComparators.OppositeImplicitComparator

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface CharComparator
extends java.util.Comparator<java.lang.Character>

A type-specific Comparator; provides methods to compare two primitive types both as objects and as primitive types.

Note that fastutil provides a corresponding abstract class that can be used to implement this interface just by specifying the type-specific comparator.

Method Summary

Modifier and Type	Method and Description
default int	compare(java.lang.Character ok1, java.lang.Character ok2) Deprecated. Please use the corresponding type-specific method instead.
int	compare(char k1, char k2) Compares its two primitive-type arguments for order.
default CharComparator	reversed()
default CharComparator	thenComparing(CharComparator second) Return a new comparator that first uses this comparator, then uses the second comparator if this comparator compared the two elements as equal.

Method Detail

compare

int compare(char k1,
            char k2)

Compares its two primitive-type arguments for order. Returns a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.

Returns:

a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.
