MindFusion.Diagramming.PatternRouter Class | JavaScript Diagram Library

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

Namespace: MindFusion.Diagramming
File: PatternRouter.js

Syntax

JavaScript Copy Code
// class PatternRouter.prototype = {}

Remarks

You can add custom patterns to the patterns property, 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.

JavaScript Copy Code
var rightZigzag = new RoutePattern(); rightZigzag.steps.push( new RouteStep(RouteStepKind.AdvanceRelative, 0.5)); rightZigzag.steps.push( new RouteStep(RouteStepKind.TurnRight)); rightZigzag.steps.push( new RouteStep(RouteStepKind.AdvanceRelative, 1)); rightZigzag.steps.push( new RouteStep(RouteStepKind.TurnLeft)); rightZigzag.steps.push( new RouteStep(RouteStepKind.AdvanceRelative, 0.5)); router.patterns.push(rightZigzag); // this can be defined in shorter form using a pattern string // var rightZigzag = new RoutePattern( // "ADR0.5 TRR ADR1 TRL ADR0.5");

JavaScript

Copy Code

var rightZigzag = new RoutePattern();
rightZigzag.steps.push(
    new RouteStep(RouteStepKind.AdvanceRelative, 0.5));
rightZigzag.steps.push(
    new RouteStep(RouteStepKind.TurnRight));
rightZigzag.steps.push(
    new RouteStep(RouteStepKind.AdvanceRelative, 1));
rightZigzag.steps.push(
    new RouteStep(RouteStepKind.TurnLeft));
rightZigzag.steps.push(
    new RouteStep(RouteStepKind.AdvanceRelative, 0.5));
router.patterns.push(rightZigzag);

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