public class FreeWorkflowLayoutController

extends LayoutController

The FreeWorkflowLayoutController is a concrete LayoutController class used to layout a free workflow. In a free workflow, visual nodes are not automatically positioned but are placed freely within the workflow view.

This specialized LayoutController uses a dynamic EdgeLayout, which means that the workflow's visual edges are repositioned after every VisualNode change. For instance, when a VisualNode is moved, the all visual edges are repositioned so that they do not intersect it.

A dynamic EdgeLayout is created with a default configuration. In order to change this default, please view the documentation of class DefaultEdgeLayout.

FreeWorkflowLayoutController

public FreeWorkflowLayoutController(LayoutController layoutController,
                                    VisualGraphObjectContainer visualgraphobject)

Constructor that create a FreeWorkflowLayoutController for the VisualGraphObjectContainer given by visualgraphobject that used the LayoutService given by service.

Parameters:

layoutController - the FreeWorkflowLayoutController to copy from.

visualgraphobject - the VisualGraphObjectContainer the layout controller should be created for

Method Detail

init

protected void init()

Description copied from class: LayoutController

This method must be overwritten by derived LayoutControllers. It should be used to register necessary Layout and define the according layout-contexts.

Specified by:

init in class LayoutController

deepCopy

public LayoutController deepCopy(VisualGraphObjectContainer visualgraphobject)

Creates a new independent layout-controller associated with the given VisualGraphObjectContainer.

Specified by:

deepCopy in class LayoutController

Parameters:

visualgraphobject - the VisualGraphObjectContainer the copy is to be associated with.

Returns:

a deep-copy of the instance.
