Package it.unimi.dsi.fastutil.doubles
Interface DoubleComparator
- All Superinterfaces:
Comparator<Double>
- All Known Implementing Classes:
AbstractDoubleComparator
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
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(double k1, double 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.
