Inheritance	PortConstraintEnforcementStage AbstractLayoutStage YObject Object

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);
