Class MessageChain

java.lang.Object
net.minecraft.network.message.MessageChain

public class MessageChain extends Object
A class for handling the "message chain".

A message chain (since 1.19.3) is implemented using an integer that is incremented for each message, called "index". MessageLink represents the link that a particular message has.

Clients signing a message with its preceding message's index is called "packing", and the server creating a signed message with its preceding message's index is called "unpacking". Unpacked messages can then be verified to check the chain's legitimacy.
