ActivityDiagramLayouter

@OpenApi
public ActivityDiagramLayouter()

ActivityDiagramLayouter

@OpenApi
public ActivityDiagramLayouter(java.lang.String optionId)

Construct ActivityDiagramLayouter

Parameters:

optionId - activity diagram layouter options id

Method Detail

layout

@OpenApi
protected boolean layout(AbstractDiagramLayouterOptionsGroup opt,
                         DiagramPresentationElement dpe,
                         UMLGraph graph)

Description copied from class: AbstractDiagramLayouter

Layouts a diagram

Overrides:

layout in class HierarchicDiagramLayouter

Parameters:

opt - layouter options

dpe - diagram to layout

graph - a constructed graph from the diagram

Returns:

true if it was layouted successfully , false otherwise.

runActivityIHLLayoutSeries

private void runActivityIHLLayoutSeries(UMLGraph graph,
                                        ActivityLayouterOptionsGroup options,
                                        y.layout.hierarchic.IncrementalHierarchicLayouter layouter)

createSwimlanePartitions

private void createSwimlanePartitions(DiagramPresentationElement dpe,
                                      ActivityLayouterOptionsGroup options,
                                      UMLGraph graph)

Creates information about swimlane and maps it to partition grid. Does that only if all diagram is layouted and it contains swimlanes, or if a swimlane is selected

Parameters:

dpe - diagram

options - layout options

graph - current graph

moveShapesToBeginningOfCell

private static void moveShapesToBeginningOfCell(UMLGraph graph,
                                                ActivityLayouterOptionsGroup options)

afterLayout

protected void afterLayout(AbstractDiagramLayouterOptionsGroup options,
                           DiagramPresentationElement dpe,
                           UMLGraph graph,
                           com.nomagic.magicdraw.commands.MacroCommand mc)

moveElementsByFakeEdges

private static void moveElementsByFakeEdges(UMLGraph graph,
                                            java.lang.String orientation)

Moves elements like pins according to the fake edges that are connected to them. Input pin is put where fake target edge connects etc.

Parameters:

graph - the graph

orientation - orientation

moveToAppropriateFrameEdge

private static void moveToAppropriateFrameEdge(DiagramPresentationElement dpe,
                                               UMLGraph graph,
                                               java.lang.String orientation)

Moves shapes on diagram frame to appropriate frame. If shape has outgoing relations and orientation is set to top to bottom, then it should be placed on top and etc.

Parameters:

dpe - diagram

graph - layouted graph

orientation - layout orientation

preProcessing

protected void preProcessing(AbstractDiagramLayouterOptionsGroup options,
                             DiagramPresentationElement dpe,
                             com.nomagic.magicdraw.commands.MacroCommand mc)

calculateLayerSizeByChildren

private static int calculateLayerSizeByChildren(UMLGraph graph,
                                                java.lang.String orientation,
                                                int percentageToTrim)

Finds a largest pin in graph after removing extreme values.

Parameters:

graph - full graph

orientation - diagram orientation

percentageToTrim - trims the defined percentage of longest pins

Returns:

the size of the largest pin, 0 if not found.

containsSelectedFromTheSameParent

protected boolean containsSelectedFromTheSameParent(DiagramPresentationElement dpe)

Activity layouter should also consider when nodes in swimlanes are selected and layouted.

Parameters:

dpe - diagram

Returns:

true if selected in same cell(can also have elements that are owned by whole swimlane)

isInDifferentSwimlanes

private static boolean isInDifferentSwimlanes(java.lang.Iterable<PresentationElement> selectedRoots)

isInSameCell

private static boolean isInSameCell(java.lang.Iterable<PresentationElement> selectedRoots)
