Javolution is a real-time library aiming to make Java 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 provides numerous high-performance classes and utilities useful to non real-time applications as well. Such as:
- Algorithmic parallel computing support with concurrent contexts.[2]
- High performance implementation of standard Java packages (such as the javolution.util [3] package holding real-time java.util [4] collections implementations).
- Context[5] programming in order to achieve true separation of concerns (logging, performance, etc).
- ValueType [6] and Stack [7] allocation support (thread-local pools or RTSJ ScopedMemory).
- Struct [8] and Union [9] base classes for direct interfacing with native applications.
- 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] working with existing Java classes and supporting references (including circular references).
- Simple yet powerful configuration management [12] for your application.
The library is also fully RTSJ compliant (does not cause memory clash or an illegal access error with RTSJ Virtual Machines).
