Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`ConnectionSet`	`getConnectionSet()`	Returns a connection set representing the graph structure after the change was applied
`ParentMap`	`getParentMap()`	Returns a parent map representing the group structure after the change was applied
`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 )
`CellView[]`	`getViews(GraphLayoutCache view)`	Allows a `GraphLayoutCache` to retrieve an array of `CellViews` that was previously stored with `putViews(GraphLayoutCache, CellView[])`.
`void`	`putViews(GraphLayoutCache view, CellView[] cellViews)`	Allows a `GraphLayoutCache` to store cell views for cells that have been removed.

- Method Detail
  - getConnectionSet
```
ConnectionSet getConnectionSet()
```
    Returns a connection set representing the graph structure after the change was applied
    
    Returns:
    
    the connection set of the graph after the change
  - getPreviousConnectionSet
```
ConnectionSet getPreviousConnectionSet()
```
    Returns a connection set representing the graph structure before the change was applied ( an "undo" of the change).
    
    Returns:
    
    the connection set of the graph before the change
  - getParentMap
```
ParentMap getParentMap()
```
    Returns a parent map representing the group structure after the change was applied
    
    Returns:
    
    the changed parent map
  - getPreviousParentMap
```
ParentMap getPreviousParentMap()
```
    Returns a parent map representing the group structure before the change was applied ( an "undo" of the change )
    
    Returns:
    
    the previous parent map
  - putViews
```
void putViews(GraphLayoutCache view,
              CellView[] cellViews)
```
    Allows a GraphLayoutCache to store cell views for cells that have been removed. Such cell views are used for re-insertion and restoring the visual attributes.
    
    Parameters:
    
    view - the GraphLayoutCache to store the removed cells
    
    cellViews - the cell views to be stored
  - getViews
```
CellView[] getViews(GraphLayoutCache view)
```
    Allows a GraphLayoutCache to retrieve an array of CellViews that was previously stored with putViews(GraphLayoutCache, CellView[]).
    
    Parameters:
    
    view - the GraphLayoutCache whose stored cells are to be retrieved
