Method used to display error messages that get caught while executing methods in the queue.

displayEvent

public void displayEvent()

displayResult

public void displayResult()

buildSnapshot

public void buildSnapshot(Object elem)

Visualizes the current elements in the snapshot iterator.

buildQueue

public void buildQueue()
                throws Exception

Visualizes the queue by shattering encapsulation, using the dataobject to access your private array that stores all the information for your queue. Since we want to visualize your queue as accurately as possible we use the front index and the size to determine what to display. So if your queue isn't visualizing the way it should be, you should check your index for the front and/or how you keep track of your size.

Throws:

Exception

addPaneLabel

public void addPaneLabel(JPanel pane,
                         String lab)

getNextLeft

public int getNextLeft()

createBox

public void createBox(int boxType,
                      String lab,
                      int left,
                      boolean iter)

Visualizes the elements for the queue or iterator.

main
