Följande kodexempel visar användningen av gränssnittet ISmartMarkerCallBack för att definiera en ny klass som hanterar callback för WorkbookDesigner.process metoden.

// 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);
}
}

För att hålla exemplet enkelt och koncis, skapar följande kodsnutt en tom designer spreadsheet, infogar en Smart Marker och bearbetar den med den dynamiskt skapade datakällan.

// 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);
