Class BroadcastMessage

java.lang.Object

protocols.broadcast.flood.messages.BroadcastMessage
public class BroadcastMessage extends pt.unl.fct.di.novasys.babel.protocols.dissemination.messages.IdentifiableProtoMessage
The flood's own wire message. It extends IdentifiableProtoMessage, the canonical ParadigmShift base for broadcast messages: a UUID message-id (the "MID") is generated when the broadcast protocol creates the message, carried unchanged across every hop, and used to deduplicate. The broadcast protocol dedups on IdentifiableProtoMessage.getMID() and calls generateDeliveryNotification(short) to build the application-facing BroadcastDelivery — so the message id lives on the message, not in the protocol's send path. (Same pattern as the production GossipMessage.)

Besides the inherited MID it carries the original sender and the issue timestamp (so every receiver reconstructs an identical delivery) and the opaque application payload.
