Class SplitEdgeLayoutStage

java.lang.Object
  y.layout.organic.SplitEdgeLayoutStage

All Implemented Interfaces:

Layouter, LayoutStage

public class SplitEdgeLayoutStage
extends Object
implements LayoutStage

This layout stage replaces edges by a path of nodes before it calls a core layouter. After the core layouter is finished this stage transforms the substituted path of nodes back to the original edge. For each node in the path there will be a bend in the original edge. The coordinate of the bend will be the center coordinate of the corresponding path node.

Constructor Detail

SplitEdgeLayoutStage

public SplitEdgeLayoutStage()

Creates a new instance of SplitEdgeLayouter

Method Detail

setSplitSegmentLength

public void setSplitSegmentLength(double l)

Sets the split segment length. The split segment length determines the length of the path that will replace an original edge in the graph. The length of the original edge path divided by the given split segment length yields the number of nodes on the new node path.

getSplitSegmentLength

public double getSplitSegmentLength()

Returns the split segment length.
