Package net.minecraft.server.network
Class ServerLoginNetworkHandler
java.lang.Object
net.minecraft.server.network.ServerLoginNetworkHandler
- All Implemented Interfaces:
PacketListener
,ServerLoginPacketListener
,ServerPacketListener
,TickablePacketListener
public class ServerLoginNetworkHandler
extends Object
implements TickablePacketListener, ServerLoginPacketListener
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
