ValidatedBeanListTableModel

public class BufferedBeanListTableModel<T>
extends BeanListTableModel<T>
implements ChangeBufferTableModel<T>

This class overrides BeanListTableModel to add change tracking. Changes to cells are queued by BeanListTableModel.setValueAt(Object, int, int). The following methods are used to update pending changes for rows:

• queueAdd(Object)
• queueAdd(int, Object) (cancelled by queueDelete(Object)
• queueDelete(Object)
• undoChangedAt(int, int)
• undoDelete(int)

The commit() method should be called after all pending changes have been saved. The revert() method is used to revert all pending changes.

                        int columnIndex)

Overrides:

setValue in class BeanListTableModel<T>

getChangedRows

public java.util.stream.Stream<T> getChangedRows()

Specified by:

getChangedRows in interface ChangeBufferTableModel<T>

Returns:

updated, added and deleted rows.

getPendingAdds

added and changed rows.

revert

public void revert()

Description copied from interface: ChangeBuffer

Undo any pending changes.

Specified by:

revert in interface ChangeBuffer

commit

public void commit()

Description copied from interface: ChangeBuffer

Save any pending changes.

Specified by:

commit in interface ChangeBuffer

isChanged

Specified by:

isChanged in interface ChangeBuffer

Returns:

true if there are pending changes

isChangedAt

public boolean isChangedAt(int rowIndex,
                           int columnIndex)

Specified by:

isChangedAt in interface ChangeBufferTableModel<T>

undoChangedAt

public void queueAdd(T bean)

Description copied from interface: ChangeBufferTableModel

Append an unsaved bean.

Specified by:

queueAdd in interface ChangeBufferTableModel<T>

                     T bean)

Description copied from interface: ChangeBufferTableModel

Insert an unsaved bean.

Specified by:

queueAdd in interface ChangeBufferTableModel<T>

queueDelete

public boolean queueDelete(T bean)

Specified by:

queueDelete in interface ChangeBufferTableModel<T>

Returns:

true if the delete was queued, false if the row was an unsaved addition and was deleted immediately.
