Class AbstractFormulaChangeMonitor

java.lang.Object

com.aspose.cells.AbstractFormulaChangeMonitor

public abstract class AbstractFormulaChangeMonitor
extends java.lang.Object

Monitor for user to track the change of formulas during certain operations.

Remarks

For example, while deleting/inserting range of cells, formulas of other cells may be changed because of the shift of references.

Example

 
         class MyFormulaChangeMonitor extends AbstractFormulaChangeMonitor
         {
             private final WorksheetCollection mWorksheets;
             public MyFormulaChangeMonitor(WorksheetCollection worksheets)
             {
                 mWorksheets = worksheets;
             }
             public /*override*/ void onCellFormulaChanged(int sheetIndex, int rowIndex, int columnIndex)
             {
                 System.out.println("Cell " + mWorksheets.get(sheetIndex).getName() + "!"
                     + CellsHelper.cellIndexToName(rowIndex, columnIndex)
                     + "'s formula was changed while inserting rows.");
             }
         }
         Workbook wb = new Workbook("template.xlsx");
         InsertOptions options = new InsertOptions();
         options.setFormulaChangeMonitor(new MyFormulaChangeMonitor(wb.getWorksheets()));
         wb.getWorksheets().get(0).getCells().insertRows(0, 2, options);
