EventCollection (jBPM :: Persistence API 7.66.0-SNAPSHOT API)

All Superinterfaces:

Serializable

All Known Implementing Classes:

BaseEventCollection
```
public interface EventCollection
extends Serializable
```
EventCollection is responsible for efficient mechanism to keep events provided to it. It's usually a short lived object and thus should not use any persistent storage. It's up to concrete implementation how to react to different type of events:
- add
- update
- remove
For instance one implementation will simply collect all type of events (reducing by duplicates) while another will filter out to keep track of only active items
