  com.tensegrity.graph.layout.tree.TreeLayoutConstants

public class TreeLayoutConstants

extends java.lang.Object

This class contains attributes as well as their default values and is used primarily by class TreeLayout.

The TreeLayout provides four different arrangement style. The following attribute may be used to specify one of them

• LAYOUT_STYLE_PLAIN
• LAYOUT_STYLE_RADIAL
• LAYOUT_STYLE_LOOP
• LAYOUT_STYLE_HV

The distance between nodes is adjustable. You can use the following attributes to set the distance between them:

• NODE_DISTANCE_DESC
• LAYER_DISTANCE_DESC
• ROTATION_DEGREE_DESC
