Interface IntComparator

All Superinterfaces:

Comparator<Integer>

All Known Implementing Classes:

AbstractIntComparator

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 IntComparator
extends Comparator<Integer>

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	Description
int	compare(int k1, int k2)	Compares its two primitive-type arguments for order.
default int	compare(Integer ok1, Integer ok2)	Deprecated. Please use the corresponding type-specific method instead.
default IntComparator	reversed()
default IntComparator	thenComparing(IntComparator second)	Return a new comparator that first uses this comparator, then uses the second comparator if this comparator compared the two elements as equal.
default Comparator<Integer>	thenComparing(Comparator<? super Integer> second)

Method Details

compare

int compare(int k1, int 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.

reversed

default IntComparator reversed()

reversed in interface Comparator<Integer>

compare

@Deprecated default int compare(Integer ok1, Integer ok2)

Deprecated.

Please use the corresponding type-specific method instead.

This implementation delegates to the corresponding type-specific method.

Specified by:

compare in interface Comparator<Integer>

thenComparing

default IntComparator thenComparing(IntComparator second)

Return a new comparator that first uses this comparator, then uses the second comparator if this comparator compared the two elements as equal.
