Class LayeredVisualizationExample

java.lang.Object
jline.examples.java.basic.LayeredVisualizationExample
public class LayeredVisualizationExample extends Object
Demonstrates JUNG visualization of LayeredNetwork models using the plot() method.

This example creates layered queueing network models and displays them using the built-in plot() method. The visualization showcases the structure of complex multi-tier software architectures.

The visualization uses shape coding:

  • Red pyramids: Processors/Hosts
  • Red parallelograms: Tasks
  • Red rectangles: Entries
  • Red circles: Activities

Edge styles indicate relationship types (all edges are black):

  • Solid lines: Parent-child containment, entry-to-activity binding, activity precedence
  • Dashed lines: Synchronous calls
  • Dot-dashed lines: Asynchronous calls
  • Dotted lines: Forwarding calls

The window includes menus for switching layouts and mouse modes.

  • Method Details

    • createForwardingExample

      public static LayeredNetwork createForwardingExample()
      Creates a simple model demonstrating forwarding calls.

      In this model:

      • Client calls Server1
      • Server1 forwards the reply to Server2 (50% probability)
      • Server2 sends the reply back to Client
      Returns:
      LayeredNetwork with forwarding calls

    • main

      public static void main(String[] args) throws Exception
      Main method demonstrating the plot() method on LayeredNetwork.
      Parameters:
      args - command line arguments (not used)
      Throws:
      Exception - if model creation fails
