Class SnapOuterPortsToNodeBorderStage

java.lang.Object
  y.layout.AbstractLayoutStage
      y.layout.router.SnapOuterPortsToNodeBorderStage

All Implemented Interfaces:

Layouter, LayoutStage

public class SnapOuterPortsToNodeBorderStage
extends AbstractLayoutStage

SnapOuterPortsToNodeBorderStage moves edge ports that are outside the corresponding area of the nodes to their border. Thus, it guarantees that ports are always in the interior of the nodes or on their borders.
