Class Command

java.lang.Object
it.polito.appeal.traci.protocol.Command
public class Command extends Object
Represents a single TraCI command, with its identifier and content. It can be used either as a request (i.e. from client to server) and as a response (i.e. from server to client). The "command" term reflects the description in the wiki. Each command is characterized by a type identifier and a variable-sized content. The command can be constructed either from a data block (a Storage) or from scratch; its content can be read or written to a Storage.
