Class TikZEdgeRouter

java.lang.Object

jline.io.tikz.TikZEdgeRouter

public class TikZEdgeRouter
extends Object

Routes edges around nodes to achieve a planar graph layout. This is a general-purpose edge routing algorithm for queueing network diagrams. It handles: - Forward edges: routes around any intermediate nodes - Backward edges (feedback loops): routes around the entire network - Self-loops: routes above/below the node - Vertical edges: routes with horizontal offset - Multiple edges to same target: staggers entry points The algorithm ensures a planar layout where edges don't cross nodes and parallel edges are visually separated.

Method Details

computeWaypoints

public List<double[]> computeWaypoints(Node from,
 Node to,
 List<Node> allNodes)

Computes waypoints for an edge to avoid overlapping nodes. Handles forward edges, backward edges, self-loops, and vertical edges.

Parameters:

from - Source node

to - Target node

allNodes - All nodes in the network

Returns:

List of waypoints (x, y pairs). Empty if straight line is OK.

isSelfLoop

public boolean isSelfLoop(Node from,
 Node to)

Checks if this edge is a self-loop.

renderRoutedEdge

public static String renderRoutedEdge(String fromId,
 String toId,
 String fromAnchor,
 String toAnchor,
 List<double[]> waypoints,
 double prob,
 TikZOptions options)

Generates TikZ code for a routed edge with waypoints.
