comparator library

Provides default Comparator constructors, and various static extension methods to modify and perform common operations on Comparator functions.

Mixins

CompareOperators<T>

A generic mixin that provides standard comparison operators like <, <=, >= and > provided the class is Comparable.

Functions

delegateComparator<T, R extends Comparable<R>>(R transformation(T value)) → Comparator<T>

Creates a comparator that compares values of type T but delegates the decision to a Comparable<R> with the provided transformation.

explicitComparator<T>(Iterable<T> iterable) → Comparator<T>

Returns an explicit Comparator based on an iterable of elements.

keyOf<T, R extends Comparable<R>>(R transformation(T value)) → Comparator<T>

Creates a comparator that compares values of type T but delegates the decision to a Comparable<R> with the provided transformation.

naturalComparable<T extends Comparable<T>>(T a, T b) → int

Natural static Comparator function using Comparable arguments.

naturalCompare(Object? a, Object? b) → int

Natural dynamic Comparator function.

reverseComparable<T extends Comparable<T>>(T a, T b) → int

Reversed static Comparator function using Comparable arguments.

reverseCompare(Object? a, Object? b) → int

Reversed dynamic Comparator function.
