| - | ... | + | Hammurapi Group Event Bus is a Java library for dispatching events to event handlers. It also has forward-reasoning capabilities. Event Bus can be used for complex event stream processing and as a forward-reasoning inference engine. |

| + | * Predicate (condition) chaining. | ||
| + | * Handler (event) chaining. | ||
| + | * Infinite inference loop detection and prevention. | ||
| + | * Live changes in the bus structure (add/remove handlers). | ||
| + | * Java binding | ||
| + | * Method and parameter level annotations to wrap Java methods into handlers. | ||
| + | * Scripted method and parameter level conditions. | ||
