PatternRouter Class

Routes links by applying patterns of segment and turn sequences and accepting them when resulting paths do not cross nodes.

Namespace: MindFusion.Diagramming
Assembly: MindFusion.Diagramming

 Syntax

C#

public class PatternRouter : ILinkRouter

Visual Basic

Public Class PatternRouter
    Implements ILinkRouter

 Remarks

You can add custom patterns to the Patterns list, or replace the standard patterns altogether. Patterns are defined using RoutePattern and RouteStep objects.

 Example

The following code defines a Z-like link route that will be accepted if it does not cross Obstacle nodes, nor passes by them within MinimumDistance.

C#

var rightZigzag = new RoutePattern();
rightZigzag.Steps.Add(
    new RouteStep(RouteStepKind.AdvanceRelative, 0.5f));
rightZigzag.Steps.Add(
    new RouteStep(RouteStepKind.TurnRight));
rightZigzag.Steps.Add(
    new RouteStep(RouteStepKind.AdvanceRelative, 1));
rightZigzag.Steps.Add(
    new RouteStep(RouteStepKind.TurnLeft));
rightZigzag.Steps.Add(
    new RouteStep(RouteStepKind.AdvanceRelative, 0.5f));
router.Patterns.Add(rightZigzag);

// this can be defined in shorter form using a pattern string
// var rightZigzag = new RoutePattern(
//     "ADR0.5 TRR ADR1 TRL ADR0.5");
