  constructor(socket) {
    super();
    socket.on("data", this.onData.bind(this));
  }

  processCmd(cmdTokens) {
    if (cmdTokens[0] === "VALUE") {
      this.initiatePending(cmdTokens, +cmdTokens[3]);
    } else {
      return false; // unknown command
    }
  }

  receiveResult(result) {
    // result: { data, cmd, cmdTokens }
    // cmd: the command that initiate the result data
