delegate-go

delegate-go provides communication between the cmd-stream-go client and server.

It contains implementations of the base.ClientDelegate and base.ServerDelegate interfaces (they are located in the corresponding packages).

A feature of this module is the system data that the server sends to the client. First of all it sends ServerInfo, than ServerSettings.

With ServerInfo you can define, for example, cmdspace, which can identify a set of commands supported by the server. If ServerInfo of the client does not match with ServerInfo received from the server, the client creation will end in an error.

With ServerSettings you can define maximum command size supported by the server. The client should not send commands of a larger size.

In turn, each of the delegates depends on an abstract transport that delivers data from the client to the server and vice versa.

Also in the client package you can find KeepaliveDelegate and ReconnectDelegate.

KeepaliveDelegate starts playing the Ping-Pong game with the server when there are no commands to send - it sends the Ping command and receives the Pong result, both of which are transmitted as a 0 (like a ball) byte.

ReconnectDelegate is an implementation of the base.ClientReconnectDelegate interface, it has a Reconnect method that can be used by the client if the connection to the server has been lost.
