Toolkit - Generate Graphs
From Gephi:Wiki
This Toolkit Example is part of the toolkit-demos project, that can be download from the website.
Demo
Demo how to generate a graph with generators. The code shows how to use RandomGraph and WattsStrogatz generators and push result into the graph structure using ImportController.
In Gephi import and generate are not directly appened to the main graph structure for consistency reasons. New data are pushed in a Container and then appened to the graph structure with the help of a Processor.
In this demo, two workspaces are created. Manipulate workspaces from ProjectController
//Init a project - and therefore a workspace ProjectController pc = Lookup.getDefault().lookup(ProjectController.class); pc.newProject(); Workspace workspace = pc.getCurrentWorkspace(); //Generate a new random graph into a container Container container = Lookup.getDefault().lookup(ContainerFactory.class).newContainer(); RandomGraph randomGraph = new RandomGraph(); randomGraph.setNumberOfNodes(500); randomGraph.setWiringProbability(0.005); randomGraph.generate(container.getLoader()); //Append container to graph structure ImportController importController = Lookup.getDefault().lookup(ImportController.class); importController.process(container, new DefaultProcessor(), workspace); //Generate another graph and append it to the current workspace Container container2 = Lookup.getDefault().lookup(ContainerFactory.class).newContainer(); RandomGraph randomGraph2 = new RandomGraph(); randomGraph2.setNumberOfNodes(100); randomGraph2.setWiringProbability(0.01); randomGraph2.generate(container.getLoader()); importController.process(container2, new AppendProcessor(), workspace); //Use AppendProcessor to append to current workspace //Create new workspace Workspace workspace2 = pc.newWorkspace(pc.getCurrentProject()); pc.openWorkspace(workspace2); //Set as current workspace //Generate dynamic graph into workspace 2 Container container3 = Lookup.getDefault().lookup(ContainerFactory.class).newContainer(); DynamicGraph dynamicGraph = new DynamicGraph(); dynamicGraph.generate(container3.getLoader()); importController.process(container3, new DefaultProcessor(), workspace2);
