    private Com_Result result;

    @XmlElementWrapper(name = "commands")
    @XmlElement(name = "command")
    private List<Heartbeat_Command> commands;

    @XmlElementWrapper(name = "versions")
    @XmlElement(name = "version")
    private List<Heartbeat_Version> versions;

    public Com_Result getResult() {
        return result;
    }

    public void setResult(Com_Result result) {
        this.result = result;
    }

    public List<Heartbeat_Command> getCommands() {
        return commands;
    }

    public void setCommands(List<Heartbeat_Command> commands) {
        this.commands = commands;
    }

    public List<Heartbeat_Version> getVersions() {
