Class ReadablePacket<T extends Client<Connection<T>>>

  • All Implemented Interfaces:
    java.lang.Runnable
    public abstract class ReadablePacket<T extends Client<Connection<T>>>
extends java.lang.Object
implements java.lang.Runnable
    This class represents a Packet received from the client. All data received must have a header with 2 bytes and an optional payload. The first and second bytes is a 16 bits integer holding the size of the packet.
