Class GraphLayoutCache

  • All Implemented Interfaces:
    java.io.Serializable, CellMapper

    public class GraphLayoutCache
    extends java.lang.Object
    implements CellMapper, java.io.Serializable
    An object that defines the view of a graphmodel. This object maps between model cells and views and provides a set of methods to change these views. The view may also contain its own set of attributes and is therefore an extension of an Observable, which may be observed by the GraphUI. It uses the model to send its changes to the command history.

                                      boolean visible)
        The actual implementation of changing cells' visibility state. This method does not deal with creating the undo or updating the GraphLayoutCache correctly. The setVisible methods in this class are intended to be the main public way to change visiblilty. However, if you do not require the undo to be formed, this method is much quicker, just note that you must call updatePorts if this method returns true.

        Messaged when the user has altered the value for the item identified by cell to newValue. If newValue signifies a truly new value the model should post a graphCellsChanged event. This calls augmentNestedMapForValueChange.

        Inserts the cloned cells from the clone map and clones the passed-in arguments according to the clone map before insertion and returns the clones in order of the cells. This example shows how to clone the current selection and get a reference to the clones:
         Object[] cells = graph.getDescendants(graph.order(graph.getSelectionCells()));
         ConnectionSet cs = ConnectionSet.create(graphModel, cells, false);
         ParentMap pm = ParentMap.create(graphModel, cells, false, true);
         cells = graphLayoutCache.insertClones(cells, graph.cloneCells(cells),
                        attributes, cs, pm, 0, 0);
         
      • insert

        public void insert​(java.lang.Object cell)
        Inserts the specified vertex into the graph model. This method does in fact nothing, it calls insert edge with the vertex and the source and target port set to null. This example shows how to add a vertex with a port and a black border:
         DefaultGraphCell vertex = new DefaultGraphCell("Hello, world!");
         Map attrs = vertex.getAttributes();
         GraphConstants.setOpaque(attrs, false);
         GraphConstants.setBorderColor(attrs, Color.black);
         DefaultPort port = new DefaultPort();
         vertex.add(port);
         port.setParent(vertex);

                               java.lang.Object target)
        Inserts the specified edge into the graph model. This method does in fact nothing, it calls insert with a default connection set.
        Parameters:
        edge - the edge to be inserted
        source - the source port this edge is connected to
        target - the target port this edge is connected to
      • insert

        public void insert​(java.lang.Object[] cells)
        Inserts the specified cells into the graph model. This method is a general implementation of cell insertion. If the source and target port are null, then no connection set is created. The method uses the attributes from the specified edge and the egdge's children to construct the insert call. This example shows how to insert an edge with a special arrow between two known vertices:
         Object source = graph.getDefaultPortForCell(sourceVertex).getCell();
         Object target = graph.getDefaultPortForCell(targetVertex).getCell();
         DefaultEdge edge = new DefaultEdge("Hello, world!");
         edge.setSource(source);
         edge.setTarget(target);
         Map attrs = edge.getAttributes();
         GraphConstants.setLineEnd(attrs, GraphConstants.ARROW_TECHNICAL);

                                java.lang.Object[] children)
        Inserts the specified cell as a parent of children. Note: All cells that are not yet in the model will be inserted. This example shows how to group the current selection and pass the group default bounds in case it is later collapsed:
         DefaultGraphCell group = new DefaultGraphCell("Hello, world!");
         Object[] cells = DefaultGraphModel.order(graph.getModel(), graph
                        .getSelectionCells());
         Rectangle2D bounds = graph.getCellBounds(cells);
         if (bounds != null) {
                bounds = new Rectangle2D.Double(bounds.getX() + bounds.getWidth() / 4,
                                bounds.getY() + bounds.getHeight() / 4, bounds.getWidth() / 2,
                                bounds.getHeight() / 2);
                GraphConstants.setBounds(group.getAttributes(), bounds);

In this case the points in the view are already routed according to the new scheme when written to the command history (-> no undo).
