                  prefuse.action.layout.graph.MultiEdgePositioningLayout

public class MultiEdgePositioningLayout
extends Layout

This layout positions the edges in a graph to be half way between the nodes (as per the EdgePositioningLayout). If there are multiple node-node edges then the edge positions will be spread out along the equi-distant line between the nodes.
