Interface IntComparator
- All Superinterfaces:
java.util.Comparator<java.lang.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 java.util.Comparator<java.lang.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.

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.

- Implementation Specification:
- This implementation delegates to the corresponding type-specific method.
