Class ModelVisualizer

java.lang.Object
jline.io.ModelVisualizer
public class ModelVisualizer extends Object
Unified visualizer for both Network and LayeredNetwork models using the JUNG library.

This visualizer accepts either a Network or LayeredNetwork object and provides appropriate visual styling for each model type:

Network models (queueing networks):

  • White shapes (except Sink which is black)
  • 9 node types: Source, Sink, Queue, Delay, Fork, Join, ClassSwitch, Cache, Router
  • Sugiyama-style left-to-right hierarchical layout
  • Solid black edges

LayeredNetwork models (LQN):

  • Red shapes (yellow when selected)
  • 4 node types: Host (triangle), Task (parallelogram), Entry (rectangle), Activity (circle)
  • 4-level hierarchical layout (Host→Task→Entry→Activity)
  • 6 edge styles: solid (hierarchy), dashed (sync), dot-dashed (async), dotted (forwarding)

  • Constructor Details

    • ModelVisualizer

      public ModelVisualizer(Network model)
      Creates a visualizer for a Network model.
      Parameters:
      model - the Network to visualize

    • ModelVisualizer

      public ModelVisualizer(LayeredNetwork model)
      Creates a visualizer for a LayeredNetwork model.
      Parameters:
      model - the LayeredNetwork to visualize

  • Method Details

    • buildGraph

      public edu.uci.ics.jung.graph.Graph<ModelVisualizer.ModelVertex,ModelVisualizer.ModelEdge> buildGraph()
      Builds a JUNG graph from the underlying model.
      Returns:
      the constructed JUNG graph

    • show

      public void show()
      Displays the graph in a JFrame window with default settings.

    • show

      public void show(String title)
      Displays the graph with a custom title.
      Parameters:
      title - the window title

    • show

      public void show(String title, int width, int height)
      Displays the graph with custom title and dimensions.
      Parameters:
      title - the window title
      width - the window width
      height - the window height

    • show

      public void show(String title, int width, int height, boolean showToolbars)
      Displays the graph with custom title, dimensions, and toolbar visibility.
      Parameters:
      title - the window title
      width - the window width
      height - the window height
      showToolbars - if true, show toolbars; if false, show only the graph image

    • showWithLayout

      public void showWithLayout(edu.uci.ics.jung.algorithms.layout.Layout<ModelVisualizer.ModelVertex,ModelVisualizer.ModelEdge> layout, String title, int width, int height, boolean showToolbars)
      Displays the graph using the specified layout with optional toolbars.

    • createHierarchicalLayout

      public edu.uci.ics.jung.algorithms.layout.Layout<ModelVisualizer.ModelVertex,ModelVisualizer.ModelEdge> createHierarchicalLayout(int width, int height)
      Creates a hierarchical layout appropriate for the model type.
