Class FullSignedBabelMessageSerializer<T extends BabelMessage>

java.lang.Object

pt.unl.fct.di.novasys.babel2.channels.BasicSignedBabelMessageSerializer<T>

pt.unl.fct.di.novasys.babel2.channels.FullSignedBabelMessageSerializer<T>

Type Parameters:

T - the type of the inner BabelMessage

All Implemented Interfaces:

BabelNetworkMessageSerializer<SignedBabelMessage<T>>, BabelNetworkSerializer<SignedBabelMessage<T>>

public class FullSignedBabelMessageSerializer<T extends BabelMessage>
extends BasicSignedBabelMessageSerializer<T>

Extended serializer for SignedBabelMessage instances capable of both signing outgoing messages and forwarding already-signed messages.

When serializing an unsigned message (where SignedBabelMessage.signature() is null), this serializer uses the local PrivateKey and BabelNode identity to compute a digital signature over the serialized inner message bytes and appends the sender and signature to the output buffer. If the message already possesses a signature and sender, they are forwarded directly. Deserialization and verification behavior are inherited from BasicSignedBabelMessageSerializer.

Constructor Summary

Constructors

Constructor	Description
FullSignedBabelMessageSerializer(PrivateKey key, BabelNode myself, BabelNetworkMessageSerializer<T> innerSerializer)	Constructs a full signed message serializer with explicit private key and local node identity.
FullSignedBabelMessageSerializer(BabelNetworkMessageSerializer<T> innerSerializer, Babel runtime)	Constructs a full signed message serializer by extracting the private key and local identity from the active Babel runtime.
