Interface GraphModelEvent.GraphModelChange

All Superinterfaces:

GraphLayoutCacheEvent.GraphLayoutCacheChange

All Known Implementing Classes:

DefaultGraphModel.GraphModelEdit, DefaultGraphModel.GraphModelLayerEdit

Enclosing interface:

GraphModelEvent

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

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

getParentMap

public ParentMap getParentMap()

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

Returns:

the changed parent map

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

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

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
