it.unimi.dsi:fastutil-extra (maven): fastutil extends the Java Collections Framework by providing type-specific maps, sets, lists and priority queues with a small memory footprint and fast access and insertion; provides also big (64-bit) arrays, sets and lists, sorting algorithms, and fast, practical I/O classes for binary and text files. This module adds data structures based on references, bytes, and characters.
