Interface LongComparator

All Superinterfaces:
Comparator<Long>
All Known Implementing Classes:
AbstractLongComparator
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.

    • 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.

    • 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.
