Detailed Description

High-performance collection classes with worst case execution time behavior documented.

Whereas Java current evolution leads to more and more classes being parts of the standard library; Javolution approach is quite the opposite. It aims to provide only the quintessential classes from which all others can be derived.

FAQ:

1. Does Javolution provide immutable collections similar to the ones provided by Scala or .NET ?

   Using Javolution you may return an Immutable reference (const reference) over any object which cannot be modified including collections or maps. [code] public class UnitSystem { Set<Unit> units; public UnitSystem(Immutable<Set<Unit>> units) { this.units = units.value(); // Defensive copy unnecessary (immutable) } } ... Immutable<Set<Unit>> unitsMKSA = new FastSet<Unit>().addAll(M, K, S, A).toImmutable(); UnitSystem MKSA = new UnitSystem(unitsMKSA); [/code]
