Examples for the integration of Libavoid edge routing in ELK

ELK Libavoid Examples

This repository contains an example for using the ELK Libavoid Eclipse plug-in. The example uses one of the Eclipse plug-in templates with a command handler.

In this example, layout is invoked via the RecursiveGraphLayoutEngine. For other ways to use ELK layouts, see the ELK documentation.

The basic usage is very simple:

var engine = new RecursiveGraphLayoutEngine();
var graph = createGraph();
engine.layout(graph, new BasicProgressMonitor());

(SampleHandler.java:27-29)

The following steps are important when creating the graph:

• Set the ALGORITHM option of the graph to "de.cau.cs.kieler.kiml.libavoid"
• Assign positions and sizes to all nodes and ports
• Set the PORT_CONSTRAINTS option of nodes to FIXED_POS
• Set the PORT_SIDE option of every port to one of the values NORTH, EAST, SOUTH or WEST

The resulting edge routing can be read from the edge layout sections.
