    • disconnect

      public void disconnect(Component pMessage)
      Closes the channel with a given reason. The reason is stored for later and will be used for informational purposes (info log on server, disconnection screen on the client). This method is also called on the client when the server requests disconnection via ClientboundDisconnectPacket. Closing the channel this way does not send any disconnection packets, it simply terminates the underlying netty channel.

    • connectToLocalServer

      public static Connection connectToLocalServer(SocketAddress pAddress)
      Prepares a clientside Connection for a local in-memory connection ("single player"). Establishes a connection to the socket supplied and configures the channel pipeline (only the packet handler is necessary, since this is for an in-memory connection). Returns the newly created instance.

    • setEncryptionKey

      public void setEncryptionKey(Cipher pDecryptingCipher, Cipher pEncryptingCipher)
      Enables encryption for this connection using the given decrypting and encrypting ciphers. This adds new handlers to this connection's pipeline which handle the decrypting and encrypting. This happens as part of the normal network handshake.

    • setupCompression

      public void setupCompression(int pThreshold, boolean pValidateDecompressed)
      Enables or disables compression for this connection. If threshold is >= 0 then a CompressionDecoder and CompressionEncoder are installed in the pipeline or updated if they already exist. If threshold is invalid input: '<' 0 then any such codec are removed. Compression is enabled as part of the connection handshake when the server sends ClientboundLoginCompressionPacket.
