Class BinaryMessage

java.lang.Object

com.avaje.ebeaninternal.server.cluster.BinaryMessage

public class BinaryMessage
extends Object

Represents a relatively small independent message.

In general terms we break up a potentially large object like RemoteTransactionEvent into many smaller BinaryMessages. This is so that if they don't all fit on a single Packet we can easily break them up and put them on multiple packets.

Also note that for the Multicast approach a Packet will generally contain many messages each directed to different members of the cluster. So it would be common for many Ack, Resend and Control messages to all be contained in a single packet.
