Detailed Description

The EmptyPacket is a packet that has no information.

This packet type is a replacement for when Packet with a default constructor was used. Normally sending blank packets are not useful; however, there are a few purposes for them, such as a "keep alive" packet to keep a connection alive. If you are wanting to use a blank packet for some purpose such as a end-of-data marker or sending some message that requires no data, it is suggested that you simply derive a class from Packet that adds no data, but has a unique ID so it can be "recognized" easier.
