com.google.visualization.datasource.base.ResponseStatus
A response status holds three parameters: 1) The response type (Ok, Warning or Error). 2) The response reason type. 3) A string with an error message to the user. @author Hillel M.

    // Check signature.
    String previousSignature = dsParams.getSignature();
    if (responseStatus == null) {
      if (!StringUtils.isEmpty(previousSignature) && (data != null)
          && (JsonRenderer.getSignature(data).equals(previousSignature))) {
        responseStatus = new ResponseStatus(StatusType.ERROR, ReasonType.NOT_MODIFIED, null);
      } else {
        responseStatus = new ResponseStatus(StatusType.OK, null, null);
      }
    }


    StatusType statusType = responseStatus.getStatusType();
    sb.append(",status:'").append(statusType.lowerCaseString()).append("'");
