Interface BabelNetworkMessageSerializer<T extends BabelMessage>

Type Parameters:

T - the concrete BabelMessage type handled by this serializer

All Superinterfaces:

BabelNetworkSerializer<T>

All Known Implementing Classes:

BabelMessageSerializer, BasicSignedBabelMessageSerializer, FullSignedBabelMessageSerializer

public interface BabelNetworkMessageSerializer<T extends BabelMessage>
extends BabelNetworkSerializer<T>

Serializer contract for Babel IP network messages.

Extends BabelNetworkSerializer with a numeric identifier that is embedded in the wire frame immediately after the Babel magic number. The receiving side reads this identifier and looks up the matching deserializer in the SerializerRegistry, allowing heterogeneous message types to share the same channel.

Concrete implementations are generated at compile time by the MessageProcessor annotation processor for every record annotated with BabelIPMessage. Each generated class is registered as a service provider via @AutoService(BabelNetworkMessageSerializer.class).
