    com.aspose.cells.AbstractCalculationMonitor

public abstract class AbstractCalculationMonitor 
extends java.lang.Object

public java.lang.Object getOriginalValue()

Gets the old value of the calculated cell. Should be used only in beforeCalculate(int, int, int) and afterCalculate(int, int, int).

public boolean getValueChanged()

Whether the cell's value has been changed after the calculation. Should be used only in afterCalculate(int, int, int).

public java.lang.Object getCalculatedValue()

Gets the newly calculated value of the cell. Should be used only in afterCalculate(int, int, int).

public void beforeCalculate(int sheetIndex, int rowIndex, int colIndex)

Implement this method to do business before calculating one cell.

Parameters:

sheetIndex - Index of the sheet that the cell belongs to.

rowIndex - Row index of the cell

colIndex - Column index of the cell

public void afterCalculate(int sheetIndex, int rowIndex, int colIndex)

Implement this method to do business after one cell has been calculated.

Parameters:

sheetIndex - Index of the sheet that the cell belongs to.

rowIndex - Row index of the cell

colIndex - Column index of the cell

public boolean onCircular(java.util.Iterator circularCellsData)

Implement this method to do business when calculating formulas with circular references.

In the implementation user may also set the expected value as calculated result for part/all of those cells so the formula engine will not calculate them recursively.

Parameters:

circularCellsData - IEnumerator with CalculationCell items representing cells that depend on circular references.

Returns:

Whether the formula engine needs to calculate those cells in circular after this call. True to let the formula engine continue to do calculation for them. False to let the formula engine just mark those cells as Calculated.
