getGameMessageHandlers

Gets the handlers for game messages, which includes providing queue implementations for the incoming and outgoing messages, as well as a counter for incoming game messages, to avoid processing too many packets per cycle. The default implementation offers a ConcurrentLinkedQueue for both of the queues, and has a limit of 10 user packets, and 50 client packets. Only packets for which the server has registered a listener will be counted towards these limitations. Most packets will count towards the 10 user packets, as the client limitation is strictly for packets which cannot directly be influenced by the user. If either of the limitations is hit during message decoding, the decoding is halted immediately until after the game has polled the incoming messages. This means the TCP protocol is responsible for ensuring too much data cannot be passed onto us.
