Java 實時集合框架：Javolution

Javolution 提供一個高性的Java集合（collection ）類庫和一些實用的工具類。雖然這個類包只提供非常少的幾個集合類，但是這些類就能夠代替大部分java.util類。javolution可以讓你的應用程序更加快速和更實時。

Javolution 主要用在對實時性要求很強的應用中，對集合操作的耗時更加可預測。

• Minimalistic - Collection classes, supporting custom views, closure-based iterations, map-reduce paradigm, parallel computations, etc.
• Optimized - To reduce the worst case execution time documented through annotations.
• Innovative - Fractal-based structures to maintain high-performance regardless of the size of the data.
• Multi-Cores Ready - Most parallelizable classes (including collections) are either mutex-free (atomic) or using extremely short locking time (shared).
• OSGi Compliant - Run as a bundle or as a standard library. OSGi contexts allow cross cutting concerns (concurrency, logging, security, ...) to be addressed at run-time through OSGi published services without polluting the application code (Separation of Concerns).
• Interoperable - Struct and Union base classes for direct interfacing with native applications. Development of the Javolution C++ library to mirror its Java counterpart and makes it easy to port any Java application to C++ for native compilation (maven based) or to write Java-Like code directly in C++ (more at Javolution C++ Overview)).
• Simple - You don't need to know the hundreds of new Java 8 util.* classes, most can be built from scratch by chaining Javolution collections or maps. No need to worry about configuration, immutability or code bloating !
• Free - Permission to use, copy, modify, and distribute this software is freely granted, provided that copyright notices are preserved (BSD License).
