decodeResponse

public static Protocol.Response decodeResponse(String payload)

Decodes a server response from a compact string format.

protocolVersion

public static int protocolVersion()

Returns the current version of the protocol code. This is used to handle backwards compatibility in the unlikely event that this very simple protocol evolves. We can't rely on clients to update themselves, so we may need to bridge the gap on the server.
