Class ReferringCellsListener

java.lang.Object
  |
  +--com.eteks.jeks.ReferringCellsListener

All Implemented Interfaces:

java.util.EventListener, javax.swing.event.TableModelListener

public class ReferringCellsListener

extends java.lang.Object

implements javax.swing.event.TableModelListener

This class records the set of the links between the computed cells of a table. The geAlltReferringCells () method allows to list all the cells which use a cell x in their formula, in the goal to optimize table updates, when x is modified. Linked to a TableModel instance, it listens to the changes of a table to update automatically all the computed cells referring to a cell.

Method Detail

addParametersReferringToCell

public void addParametersReferringToCell(JeksCell cell,
                                         JeksExpression expression)

Adds a referring link between cells cell and all the cells of the parameters of expression in the formula of cell.

Parameters:

cell - a cell.

expression - an expression using a set of cells as parameters in its formula.

removeReferringCells

public void removeReferringCells(JeksCell cell)

Removes all referring link to cell.

Parameters:

cell - a cell.

removeParametersReferringToCell

public void removeParametersReferringToCell(JeksCell cell,
                                            JeksExpression expression)

Removes all referring link between cells cell and all the cells of the parameters of expression in the formula of cell.

Parameters:

cell - a cell.

expression - an expression using a set of cells as parameters in its formula.

getReferringCells

public java.util.Vector getReferringCells(JeksCell cell)

Returns the list of all the cells referring cell as a parameter in their formula directly.

Parameters:

cell - a cell.

getAllReferringCells

public java.util.Vector getAllReferringCells(JeksCell cell)

Returns the full list of all the cells referring cell as a parameter in their formula directly or indirectly. This method is mostly used to get all the cells to update after a change of cell.

Parameters:

tableChanged

public void tableChanged(javax.swing.event.TableModelEvent event)

TableModelListener implementation

Specified by:

tableChanged in interface javax.swing.event.TableModelListener

tableUpdated

public void tableUpdated(javax.swing.table.TableModel model,
                         java.util.Vector updatedSet)
