Class DoubleLinePlacer

java.lang.Object
  y.layout.tree.AbstractRotatableNodePlacer
      y.layout.tree.DoubleLinePlacer

All Implemented Interfaces:

FromSketchNodePlacer, NodePlacer

public class DoubleLinePlacer
extends AbstractRotatableNodePlacer

The DoubleLinePlacer is a special node placer that places its children in two lines.
This node placer is especially useful for leaves with great width.
