Constructor Detail

DefaultGraphModel.GraphModelLayerEdit

public DefaultGraphModel.GraphModelLayerEdit(Object[] cells,
                                             int layer)

Constructs a GraphModelEdit. This modifies the order of the cells in the model.

Method Detail

getSource

public Object getSource()

Returns the source of this change. This can either be a view or a model, if this change is a GraphModelChange.

Specified by:

getSource in interface GraphModelEvent.GraphViewChange

Overrides:

getSource in class GraphLayoutCache.GraphViewLayerEdit

getChanged

public Object[] getChanged()

Returns the cells that have changed.

Specified by:

getChanged in interface GraphModelEvent.GraphViewChange

Overrides:

getChanged in class GraphLayoutCache.GraphViewLayerEdit

getInserted

public Object[] getInserted()

Returns the cells that have changed.

Specified by:

getInserted in interface GraphModelEvent.GraphModelChange

getRemoved

public Object[] getRemoved()

Returns the cells that have changed.

Specified by:

getRemoved in interface GraphModelEvent.GraphModelChange

getPreviousAttributes

public Map getPreviousAttributes()

Returns null.

Specified by:

getPreviousAttributes in interface GraphModelEvent.GraphModelChange

getPreviousConnectionSet

public ConnectionSet getPreviousConnectionSet()

Specified by:

getPreviousConnectionSet in interface GraphModelEvent.GraphModelChange

getPreviousParentMap

public ParentMap getPreviousParentMap()

Specified by:

getPreviousParentMap in interface GraphModelEvent.GraphModelChange

addImplicitEdit

public void addImplicitEdit(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

public CellView[] getViews(GraphLayoutCache view)

Returns the views that have not changed explicitly, but implicitly because one of their dependent cells has changed.

Specified by:

getViews in interface GraphModelEvent.GraphModelChange

putViews

public void putViews(GraphLayoutCache view,
                     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

updateListeners

protected void updateListeners()

Overrides:

updateListeners in class GraphLayoutCache.GraphViewLayerEdit

getParentList

protected List getParentList(Object cell)

Returns the list that exclusively contains view.

Overrides:

getParentList in class GraphLayoutCache.GraphViewLayerEdit
