Many programming paradigms, abstractions, design -, and architectural patterns are built on the idiom of application events. However, programming support for event-based applications is still rather specific and rudimentary.
EventJava is an extension of Java with advanced support for event-based distributed programming. EventJava:
- promotes fully asynchronous interaction seamlessly integrated with traditional synchronous method invocations.
- inherently unifies support for unicasting as well as multicasting of events.
- provides increased expressiveness by supporting reactions to event collections and especially correlation predicates guarding those reactions.
- Last but not least, EventJava is generic in that it includes a framework for customization of event semantics, to adapt event propagation and dispatching to various application scenarios. This is supported mainly by integrating a notion of event context.
