   +----jdsltools.visualization.VisualizationController
public class VisualizationController
extends Object
implements AnimationController, ContainerController, TimelineClient, ContainerVisualizerClient, ElementSelector, EnumerationDisplay, NewContainerDisplay
This is a class without visible representation that routes events among the four visualization components (ContainerVisualizer, Timeline, OperationSelector, and ElementSelector) and the student's data structure (Container).

Methods

o snapshot 
 public static void snapshot(Position pos,
                             Color eventColor)
These static methods allow students to take snapshots of their Containers using only one line of code, without instance variables and parameters to constructors. They also allow objects that do not know about Containers (nodes, for instance) to cause snapshots to be taken.

Parameters:
loc - Locator to be highlighted
eventColor - Color of event on timeline
o snapshot 
 public static void snapshot(Position pos1,
                             Position pos2,
                             Color eventColor)
o snapshot 
 public static void snapshot(Color eventColor)
These static methods allow students to take snapshots of their Containers using only one line of code, without instance variables and parameters to constructors. They also allow objects that do not know about Containers (nodes, for instance) to cause snapshots to be taken.

Parameters:
eventColor - Color of event on timeline
o snapshot 
 public static void snapshot()
These static methods allow students to take snapshots of their Containers using only one line of code, without instance variables and parameters to constructors. They also allow objects that do not know about Containers (nodes, for instance) to cause snapshots to be taken. Snapshot will appear as red in the currently active container and blue in all other ones.

o addContainer 
 public static void addContainer(Container c,
                                 String title)
Add a container with the given title to the visualizer; must implement the needed interfaces for its type of container in order for anything to happen.

Parameters:
c - Container to add
title - String to refer to container with
