Interface CellView

All Known Implementing Classes:
AbstractCellView, EdgeView, PortView, VertexView

public interface CellView
Defines the requirements for an object that represents a view for a model cell.
  • Method Details

    • getCell

      Object getCell()
      Returns the model object that this view represents.
    • refresh

      void refresh(GraphLayoutCache cache, CellMapper mapper, boolean createDependentViews)
      Refresh this view based on the model cell. This is messaged when the model cell has changed.
    • update

      void update(GraphLayoutCache cache)
      Update this view's attributes. This is messaged whenever refresh is messaged, and additionally when the context of the cell has changed, and during live-preview changes to the view.
      Parameters:
      cache - TODO
    • childUpdated

      void childUpdated()
    • getParentView

      CellView getParentView()
      Returns the parent of view of this view.
    • getChildViews

      CellView[] getChildViews()
      Returns the child views of this view.
    • removeFromParent

      void removeFromParent()
      Removes this view from the list of childs of the parent.
    • isLeaf

      boolean isLeaf()
      Returns true if the view is a leaf.
    • getBounds

      Rectangle2D getBounds()
      Returns the bounds for the view.
    • intersects

      boolean intersects(JGraph g, Rectangle2D rect)
      Returns true if the view intersects the given rectangle.
    • getPerimeterPoint

      Point2D getPerimeterPoint(EdgeView edge, Point2D source, Point2D p)
      Returns the intersection of the bounding rectangle and the straight line between the source and the specified point p. The specified point is expected not to intersect the bounds. Note: You must override this method if you use a different renderer. This is because this method relies on the VertexRenderer interface, which can not be safely assumed for subclassers.
    • changeAttributes

      Map changeAttributes(GraphLayoutCache cache, Map map)
      Apply the specified map of attributes on the view.
    • getAttributes

      AttributeMap getAttributes()
      Returns all attributes of the view as a map.
    • getAllAttributes

      AttributeMap getAllAttributes()
    • getRendererComponent

      Component getRendererComponent(JGraph graph, boolean selected, boolean focus, boolean preview)
      Returns a renderer component, configured for the view.
    • getHandle

      CellHandle getHandle(GraphContext context)
      Returns a cell handle for the view.
    • getEditor

      GraphCellEditor getEditor()
      Returns a cell editor for the view.
