  - addImplicitEdit
```
public void addImplicitEdit(javax.swing.undo.UndoableEdit edit)

    Allows a 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.

    getViews in interface GraphModelEvent.GraphModelChange
    
    Parameters:

                     CellView[] cellViews)
```
    Returns the views that have not changed explicitly, but implicitly because one of their dependent cells has changed.
    
    Specified by:
    
    putViews in interface GraphModelEvent.GraphModelChange
    
    Parameters:
    
    view - the GraphLayoutCache to store the removed cells
    
    cellViews - the cell views to be stored

    Redoes a change.

    Throws:
    
    javax.swing.undo.CannotUndoException - if the change cannot be undone
  - execute
```
public void execute()
```
    Execute this edit such that the next invocation to this method will invert the last execution.
  - updateListeners

  - getParentList
```
protected java.util.List getParentList(java.lang.Object cell)
```
    Returns the list that exclusively contains view.
