public class ChunkedMessage
extends ApplicationMessage

Models a chunked application message that can be composed by the recipient to one final message.

A chunked message sequence looks like the follow:
1. ChunkedMessage with RelayableMessage.recipient, ApplicationMessage.sender, RelayableMessage.hopCount, AbstractMessage.id, ApplicationMessage.payload, contentLength and checksum
2. - (n-1). ChunkedMessage RelayableMessage.recipient, ApplicationMessage.sender, RelayableMessage.hopCount, AbstractMessage.id and ApplicationMessage.payload
n. ChunkedMessage RelayableMessage.recipient, ApplicationMessage.sender, RelayableMessage.hopCount, AbstractMessage.id and payload := new byte[]{}
