Returns the cells that were inserted.
|
java.lang.Object |
getSource()
Returns the source of this change.
|
CellView[] |
getViews(GraphLayoutCache view)
Allows a

cells that have been removed. |
void |
redo()
Redoes a change.
|
void |
setDirtyRegion(java.awt.geom.Rectangle2D dirty)
In some cases the class firing this event will not have access
to the dirty region prior to the change.
