Interface GraphModelEvent.GraphModelChange

All Superinterfaces:

GraphModelEvent.GraphViewChange

All Known Implementing Classes:

DefaultGraphModel.GraphModelEdit, DefaultGraphModel.GraphModelLayerEdit

Enclosing class:

GraphModelEvent

public static interface GraphModelEvent.GraphModelChange
extends GraphModelEvent.GraphViewChange

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

Method Summary

Object[]	getInserted() Returns the cells that have been inserted into the model.
Map	getPreviousAttributes() Returns a map that contains (object, map) pairs of the attributes that have been stored in the model.
ConnectionSet	getPreviousConnectionSet()
ParentMap	getPreviousParentMap()
Object[]	getRemoved() Returns the cells that have been removed from the model.
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

getInserted

Object[] getInserted()

Returns the cells that have been inserted into the model.

getRemoved

Object[] getRemoved()

Returns the cells that have been removed from the model.

getPreviousAttributes

Map getPreviousAttributes()

Returns a map that contains (object, map) pairs of the attributes that have been stored in the model.

getPreviousConnectionSet

ConnectionSet getPreviousConnectionSet()

getPreviousParentMap

ParentMap getPreviousParentMap()

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.

getViews

CellView[] getViews(GraphLayoutCache view)

Allows a GraphLayoutCache to retrieve an array of CellViews that was previously stored with putViews(GraphLayoutCache, CellView[]).
