EventEmitter (jBPM :: Persistence API 7.71.0-SNAPSHOT API)

All Superinterfaces:

AutoCloseable
```
public interface EventEmitter
extends AutoCloseable
```
Emitter is the main integration point with external systems. It will be called first to get implementation of the EventCollection next depending on the PersistenceEventManager implementation will provide the actual events on three phases:
- deliver - is the first phase that gives complete view of events before persistence is completed
- apply - is kind of confirmation that persistence is completed and events can be safely transferred
- drop - is kind of rejection that persistence failed and events should be discarded

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`apply(Collection<InstanceView<?>> data)`	Indicates that given collection of events can be safely transferred to external systems
`void`	`close()`	Closes any resources used by emitter to interact with external system
`void`	`deliver(Collection<InstanceView<?>> data)`	Invoked just before persistence layer is completed - e.g. beforeCompletion in JTA transaction
`void`	`drop(Collection<InstanceView<?>> data)`	Indicates that given collection of events should be discarded
`EventCollection`	`newCollection()`	Returns new instance of EventCollection to be used while collecting events
