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. Please note, methods in the monitor may be invoked multiple times for one object which contains the formula.

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);
