Header (cloudwatch-lambda-event-dispatcher 1.0.0 API)

java.lang.Object
- com.perihelios.aws.lambda.cloudwatch.dispatcher.event.Header

```
public class Header
extends Object
```
Encapsulates the metadata from a CloudWatch event.
Every CloudWatch event includes a set of common fields; this class encapsulates those.

Note that the detail-type property is not included in this class, as it is used exclusively by the unmarshaller to identify to which subtype of CloudWatchEvent the event should be unmarshalled. The detail property is unmarshalled as the body of the identified subtype, and so is also not included in the header.
