Getting Notifications while Merging Data with Smart Markers
Get Notifications while Merging Data with Smart Markers
The following piece of code demonstrates the usage of ISmartMarkerCallBack interface to define a new class that handles the call back for WorkbookDesigner.process method.
// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java | |
public class SmartMarkerCallBack implements ISmartMarkerCallBack { | |
Workbook workbook; | |
SmartMarkerCallBack(Workbook workbook) { | |
this.workbook = workbook; | |
} | |
@Override | |
public void process(int sheetIndex, int rowIndex, int colIndex, String tableName, String columnName) { | |
System.out.println("Processing Cell : " + workbook.getWorksheets().get(sheetIndex).getName() + "!" | |
+ CellsHelper.cellIndexToName(rowIndex, colIndex)); | |
System.out.println("Processing Marker : " + tableName + "." + columnName); | |
} | |
} |
In order to keep the example simple and to the point, the following snippet creates an empty designer spreadsheet, inserts a Smart Marker and processes it with the dynamically created data source.
// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java | |
// The path to the documents directory. | |
String dataDir = Utils.getDataDir(GetNotificationsWhileMergingData.class); | |
// Instantiate a new Workbook designer | |
WorkbookDesigner report = new WorkbookDesigner(); | |
// Get the first worksheet of the workbook | |
Worksheet sheet = report.getWorkbook().getWorksheets().get(0); | |
/* | |
* Set the Variable Array marker to a cell. You may also place this Smart Marker into a template file manually using Excel | |
* and then open this file via WorkbookDesigner | |
*/ | |
sheet.getCells().get("A1").putValue("&=$VariableArray"); | |
// Set the data source for the marker(s) | |
report.setDataSource("VariableArray", new String[] { "English", "Arabic", "Hindi", "Urdu", "French" }); | |
// Set the CallBack property | |
report.setCallBack(new SmartMarkerCallBack(report.getWorkbook())); | |
// Process the markers | |
report.process(false); | |
// Save the result | |
report.getWorkbook().save(dataDir); |
