Class AutoLayout

java.lang.Object

org.gephi.layout.plugin.AutoLayout

public class AutoLayout
extends Object

Class to build layout scenario that runs for a certain duration. Multiple layout can be chained and their duration ratio set. Moreover layout property can be mananaged automatically and set in advance.

Example:

This will execute ForceAtlas for the first 80%, and LabelAdjust for remaining 20%

 AutoLayout autoLayout = new AutoLayout(10, TimeUnit.SECONDS);
 ForceAtlasLayout forceAtlasLayout = new ForceAtlasLayout(null);
 AutoLayout.DynamicProperty gravity = AutoLayout.createDynamicProperty("Gravity", new Double[]{80., 400.0}, new float[]{0f, 1f}, AutoLayout.Interpolation.LINEAR);
 AutoLayout.DynamicProperty speed = AutoLayout.createDynamicProperty("Speed", new Double[]{1.2, 0.3}, new float[]{0f, 1f}, AutoLayout.Interpolation.LINEAR);
 AutoLayout.DynamicProperty repulsion = AutoLayout.createDynamicProperty("Repulsion strength", new Double[]{3000.0, 6000.}, new float[]{0f, 1f}, AutoLayout.Interpolation.LINEAR);
 AutoLayout.DynamicProperty freeze = AutoLayout.createDynamicProperty("Autostab Strength", new Double(100.0), 0f);
 autoLayout.addLayout(forceAtlasLayout, 0.8f, new AutoLayout.DynamicProperty[]{gravity, speed, repulsion, freeze});

 //LabelAdjust
 LabelAdjust labelAdjust = new LabelAdjust(null);
 AutoLayout.DynamicProperty speed2 = AutoLayout.createDynamicProperty("Speed", new Double[]{0.5, 0.2}, new float[]{0f, 1f}, AutoLayout.Interpolation.LINEAR);
 autoLayout.addLayout(labelAdjust, 0.2f, new AutoLayout.DynamicProperty[]{speed2});
