Class GridLayouter

java.lang.Object

com.inubit.research.layouter.ProcessLayouter

com.inubit.research.layouter.gridLayouter.GridLayouter

Direct Known Subclasses:

XFormsLayouter

public class GridLayouter
extends ProcessLayouter

This Grid Layouter is an implementation of an algorithm presented in the paper "A Simple Algorithm for Automatic Layout of BPMN Processes" by Ingo Kitzmann, Christopher Koenig, Danile Luebke and Leif Singer of the Leibniz University Hannover It can be applied to BPMN and TWF diagrams. it places all objects along a grid (like in excel). positions of objects are considered while layouting, therefore a user can e.g. switch two pools and relayout.

Method Detail

layoutModel

public void layoutModel(AbstractModelAdapter model,
                        int xstart,
                        int ystart,
                        int direction)
                 throws java.lang.Exception

layouts the given model. the start coordinates and direction will be ignored as they are not needed.

Specified by:

layoutModel in class ProcessLayouter

direction - One of LAYOUT_VERTICAL or LAYOUT_HORIZONTAL

Throws:

java.lang.Exception

getMaxLaneDepth

public int getMaxLaneDepth()

Returns:

the f_maxLaneDepth

layoutDataObject

protected void layoutDataObject(FlowObjectWrapper _fow)

special handling for data objects, they are usually places on the upper right of their associated nodes. To ensure that this space is still free, they are places outside of the standard grid (multiples of Layout_right_grid_spacing)

Parameters:

_fow -

getDisplayName

public java.lang.String getDisplayName()

Specified by:

getDisplayName in class ProcessLayouter

setSelectedNode

public void setSelectedNode(NodeInterface selectedNode)

Specified by:

setSelectedNode in class ProcessLayouter

getGrids

public Hypergrid getGrids()

getProperties

public java.util.Properties getProperties()

Returns:

getUnroutedEdges

public java.util.List<EdgeInterface> getUnroutedEdges()

used only within ProcessEditor so far. To all of those edges the standard layout algorithm (by Uwe) is applied)

Overrides:

getUnroutedEdges in class ProcessLayouter

Returns:
