Javolution is a real-time library aiming to make Java or Java-Like/C++ applications faster and more time predictable. Indeed, time-predictability can easily be ruined by the use of the standard library (lazy initialization, array resizing, etc.) which is not acceptable for safety-critical systems. The open source Javolution library addresses these concerns[1] for the Java platform and native applications. It provides numerous high-performance classes and utilities useful to non real-time applications as well. Such as:
- Collections [2] classes, supporting custom views [3], closure-based iterations, map-reduce paradigm, parallel computing, etc.
- Worst-case execution time behavior documented using Realtime [4] Java annotations.
- Fractal structures [5] to maintain high-performance regardless of the size of the data.
- OSGi contexts [6] allowing cross cutting concerns (concurrency, logging, security, ...) to be addressed at run-time through OSGi published services without polluting the application code (Separation of concerns).
- Algorithmic parallel computing support with concurrent contexts. [7]
- Struct/Union [8] base classes for direct interfacing with native applications.
- Perfometer [9] utility class to measure worst-case execution time with high precision.
- Real-Time StAX-like implementation (javolution.xml.stream [10]) (does not implement StAX-API, but resembles it, uses similar naming) which does not force object creation.
- XML marshalling/unmarshalling [11].
- Simple yet powerful configuration management [12] for your application.
Since version 6.0, Javolution makes it easy to port [13] any Java source code to C++ for Cross-platform native compilation. OSGi and JUnit have been ported and are included with the core C++ distribution.
All modules (Java and native) are built using maven.
