Constructs a GraphModelEdit.
|
Modifier and Type | Method and Description |
---|---|
void |
addImplicitEdit(javax.swing.undo.UndoableEdit edit)
Allows a
GraphLayoutCache to add and execute and
UndoableEdit in this change. |
void |
execute()
Execute this edit such that the next invocation to this method will
invert the last execution.
|
java.util.Map |
getAttributes()
Returns null.
|
java.lang.Object[] |
getChanged()
Returns the cells that have changed.
|
ConnectionSet |
getConnectionSet()
Returns a connection set representing the graph structure after the
change was applied
|
java.lang.Object[] |
getContext()
Returns null.
|
java.awt.geom.Rectangle2D |
getDirtyRegion()
Returns the dirty region for the original position of the
changed cells before the change happened.
|
java.lang.Object[] |
getInserted()
Returns the cells that have changed.
|
protected java.util.List |
getParentList(java.lang.Object cell)
Returns the list that exclusively contains
view . |
ParentMap |
getParentMap()
Returns null.
|
java.util.Map |
getPreviousAttributes()
Returns null.
|
ConnectionSet |
getPreviousConnectionSet()
Returns a connection set representing the graph structure before the
change was applied ( an "undo" of the change).
|
ParentMap |
getPreviousParentMap()
Returns a parent map representing the group structure before the
change was applied ( an "undo" of the change )
|
java.lang.Object[] |
getRemoved()
Returns the cells that have changed.
|
java.lang.Object |
getSource()
Returns the source of this change.
|
CellView[] |
getViews(GraphLayoutCache view)
Returns the views that have not changed explicitly, but implicitly
because one of their dependent cells has changed.
|
void |
putViews(GraphLayoutCache view,
CellView[] cellViews)
Returns the views that have not changed explicitly, but implicitly
because one of their dependent cells has changed.
|
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.
|
void |
undo()
Undoes a change.

public void addImplicitEdit(javax.swing.undo.UndoableEdit edit)
GraphLayoutCache
to add and execute and
UndoableEdit in this change. This does also work if the parent edit
has already been executed, in which case the to be added edit will be
executed immediately, after addition. This is used to handle changes
to the view that are triggered by certain changes of the model. Such
implicit edits may be associated with the view so that they may be
undone and redone correctly, and are stored in the model's global
history together with the parent event as one unit.public CellView[] getViews(GraphLayoutCache view)
