This layout stage can be used to enforce that a layout algorithm will not change the relative coordinates of ports that are associated with a strong/fixed port constraint.

Remarks

This layout stage can be used to enforce that a layout algorithm will not change the relative coordinates of ports that are associated with a strong/fixed port constraint. Usage: 
            //prepare port constraints
            graph.addDataProvider(PortConstraintKeys.SOURCE_PORT_CONSTRAINT_KEY, createSPCs(graph));
            graph.addDataProvider(PortConstraintKeys.TARGET_PORT_CONSTRAINT_KEY, createTPCs(graph));
            //create layout pipeline
            OrganicLayouter layouter = new OrganicLayouter();
            PortConstraintEnforcementStage stage = new PortConstraintEnforcementStage();
            stage.setCoreLayouter(organic);
            //launch algorithms
            new BufferedLayouter(stage).doLayout(graph);
