Interface GraphModelEvent.GraphModelChange

public static interface GraphModelEvent.GraphModelChange extends GraphLayoutCacheEvent.GraphLayoutCacheChange

Defines the interface for objects that may be included into a GraphModelEvent to describe a model change.

Method Summary
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

public 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

getParentMap

public ParentMap getParentMap()

Returns a parent map representing the group structure after the change was applied

Returns: the changed parent map

getPreviousConnectionSet

public 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

getPreviousParentMap

public 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

getViews

public 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

putViews

public 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
