fastutil extends the Java Collections Framework by providing type-specific maps, sets, lists, and queues with a small memory footprint and fast operations; it provides also big (64-bit) arrays, sets, and lists, sorting algorithms, fast, practical I/O classes for binary and text files, and facilities for memory mapping large files. This jar (fastutil-core.jar) contains data structures based on integers, longs, doubles, and objects, only; fastutil.jar contains all classes. If you have both jars in your dependencies, this jar should be excluded.

There is a newer version: 8.5.15

 * {@link java.util.function.IntConsumer}). For types missing a type-specific JDK consumer (e.g.,
 * {@code short} or {@code float}), we extend the consumer associated with the smallest primitive
 * type that can represent the current type (e.g., {@code int} or {@code double}, respectively).
