Implement a Graph as a view of the DatasetGraph. It maps graph operations to quad operations.
fbench.graph.GraphView
A panel for displaying an Element of the DOM Tree of an IEC 61499 XML LibraryElement as a directed graph. @author JHC, JP @version 20070530/JP - GraphView extends ViewModel, most of the basic features have beentaken to ViewModel.java for better extensibility @version 20070330/JP - Display FBNetwork of Resource element when the Resource is selected on tree @version 20051129/JHC - Inhibited re-drawing in handleEvent whenMutationEvent comes from an Action (this is clumsy and will probably have to be fixed later). @version 20051109/JHC - All notifications now via DOM Event mechanism. @version 20050421/JHC

Graph view define a subgraph, i.e. a subset of the original graph. GraphModel has at least a single view, called the main view, which contains 100% of the graph. Other views can be defined by users to define subgraphs with a reduced number of nodes and edges. This is typically used by filters, which returns filtered graphs.
GraphModel also contains the visible view, which is the main view by default but can be set to configure the view that is visualized.
What exactly contains the view? The complete hierarchy of nodes, the edges and meta-edges. Each view has separate hierarchy, therefore grouping and meta-edges are independent.
Note that nodes' id is unique, and is not touched by views.
Main or Visible View?
When you need to interact with the graph structure, you have the choice between working on the complete graph, i.e. the main view, or the visible view. In most cases, it's preferable to use the visible view because your action will use the graph currently visualized, which has been potentially filtered by users on purpose.
To get the graph in the visible view, see {@link GraphModel#getGraphVisible()}.
Set the Visible View
This is the typical workflow for filtering a graph and display the results, as done by FiltersAPI.
- Create a new view, which duplicates the main view, with all nodes and edges in it.
- Remove nodes and edges in the view.
- Set the view as the curently visible view.
To set a view as the currently visible view, see {@link GraphModel#setVisibleView(org.gephi.graph.api.GraphView)}. @author Mathieu Bastian

The GraphView represents a view that paints the Graph containing the visualised Nodes and Egdes. The default painting relies upon a NodeRenderer and an EdgeRenderer.

Examples of org.gephi.graph.api.GraphView

        public Graph filter(Graph[] graphs) {
            if (graphs.length > 1) {
                throw new IllegalArgumentException("Not Filter accepts a single graph in parameter");
            }
            HierarchicalGraph hgraph = (HierarchicalGraph) graphs[0];
            GraphView hgraphView = hgraph.getView();
            HierarchicalGraph mainHGraph = hgraph.getView().getGraphModel().getHierarchicalGraph();
            for (Node n : mainHGraph.getNodes().toArray()) {
                if (n.getNodeData().getNode(hgraphView.getViewId()) == null) {
                    //The node n is not in graph
                    hgraph.addNode(n);
                } else {
                    //The node n is in graph
                    hgraph.removeNode(n);
                }
            }


            for (Node n : hgraph.getNodes().toArray()) {
                Node mainNode = n.getNodeData().getNode(mainHGraph.getView().getViewId());
                Edge[] edges = mainHGraph.getEdgesAndMetaEdges(mainNode).toArray();
                for (Edge e : edges) {
                    if (e.getSource().getNodeData().getNode(hgraphView.getViewId()) != null
                            && e.getTarget().getNodeData().getNode(hgraphView.getViewId()) != null) {
                        hgraph.addEdge(e);
