| writeData(); |
| } catch (SQLException e) { |
| // the most case is that the time series does not exist |
| if (e.getMessage().contains("exist")) { |
| //However, using the content of the error message is not so efficient |
| registerTimeSeries(); |
| //write data once again |
| writeData(); |
| } |

Different error codes are added to all exceptions. When an exception is caught and a higher-level exception is thrown, the error code will keep and pass so that users will know the detailed error reason. |
| A base exception class "ProcessException" is also added to be extended by all exceptions.</p></blockquote></div> <div class="page-nav"><p class="inner"><span class="prev"> |
