This package requires Java 8.

What this is

This package aims to emulate Guava's Range for the following primitive types:

  • char,
  • int,
  • long,
  • double.

It also aims at providing, to the extent possible, an equivalent of Guava's RangeSet and RangeMap for said primitive types (and their Immutable counterparts as well).

Motivation

Range is an immensely powerful API. Unfortunately, when it comes to primitive types, you have no choice but to use boxed types for primitives, therefore you need to have a Range<Integer> instead of, say, an IntRange as this package aims to provide.

This results in code which is suboptimized for primitives; for instance, to check whether an int is within a Range<Integer>, the code will end up making calls to .compareTo() whereas simple arithmetic operations would do the job just as well, and at a lesser cost.
