Event (Delft Java Utilities Basic Classes 2.2.0 API)

java.lang.Object
- org.djutils.event.Event

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

TimedEvent
```
public class Event
extends Object
implements Serializable
```
The Event class forms the reference implementation for the Event. Because events are often sent over the network, the interface demands that its content are serializable. It is the responsibility of the programmer, though, that the fields of the content are serializable as well.
