createGraph

@OpenApi
protected UMLGraph createGraph(DiagramPresentationElement dpe,
                                        boolean useIntegratedLabels)

Constructs a graph for layout

Parameters:

dpe - shapes and edges are taken from this diagram

Returns:

a created UMLGraph

getSelected

@OpenApi
protected java.util.Set<PresentationElement> getSelected(DiagramPresentationElement diagramView)

Collects a set of selected presentation elements in a diagram

Parameters:

diagramView - the diagram that elements were selected in

Returns:

a set of selected presentation elements in a diagram

layout
