Class CEPEngine

java.lang.Object

org.eclipse.viatra.cep.core.api.engine.CEPEngine

public class CEPEngine
extends java.lang.Object

The engine for processing complex events.

The engine hosts the following components:

• a DefaultEventModelManager, dealing with the internal representation of the (partially) matched event patterns;
• a DefaultStreamManager, managing the streams of events;
• an EVM ExecutionSchema, serving as the rule engine.

An instance of the engine can be obtained either by using the default event processing context (newEngine() ), or by specifying one explicitly (#newEngine(EventContext)).

Since:

0.8
