Package net.minecraft.server.network

Class ServerLoginNetworkHandler

java.lang.Object
net.minecraft.server.network.ServerLoginNetworkHandler
All Implemented Interfaces:
PacketListener, ServerCookieResponsePacketListener, ServerCrashSafePacketListener, ServerLoginPacketListener, ServerPacketListener, TickablePacketListener
public class ServerLoginNetworkHandler extends Object implements ServerLoginPacketListener, TickablePacketListener
The server login network handler.

It listens to packets on the netty event loop and is ticked on the server thread simultaneously.

Implementation Requirements:
The vanilla implementation is created by a handshake network handler. It first receives a hello packet from the client. If it is in online mode, it goes through an additional authentication process. Then it optionally sends a network compression packet. Finally, when it can accept the player (no player UUID conflicts), it will accept the player by sending a login success packet and then transitions the connection's packet listener to a ServerPlayNetworkHandler.
