Examples of org.gdbms.engine.data.DataSource.start()

org.gdbms.engine.data.DataSource.start()
Opens the DataSource to access the data it contains. If the data is accessed without a previous opening a ClosedDataSourceException is thrown. If this method is invoked twice then only the second call to stop will close the DataSource.
If the DataSource was obtained with an AUTOMATIC_OPENING mode, there's no need to open the DataSource. Indeed start calls are ignored. It's possible to close the DataSource by a single call to the close method @throws DriverException if the operation fails
