Interface LongComparator

All Superinterfaces:

Comparator<Long>

All Known Implementing Classes:

AbstractLongComparator, LongComparators.NaturalImplicitComparator, LongComparators.OppositeComparator, LongComparators.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 LongComparator
extends Comparator<Long>

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
int	compare(long k1, long k2) Compares its two primitive-type arguments for order.
default int	compare(Long ok1, Long ok2) Deprecated. Please use the corresponding type-specific method instead.
default LongComparator	reversed()
default Comparator<Long>	thenComparing(Comparator<? super Long> second)
default LongComparator	thenComparing(LongComparator 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(long k1,
            long 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 LongComparator reversed()

compare

@Deprecated
default int compare(Long ok1,
                                Long 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<Long>

thenComparing

default LongComparator thenComparing(LongComparator second)

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