Class Graph

public class Graph
extends Object

The scene's Graph basically stores the scene content and facilitate objects control The graph may decompose all AbstractComposite into a list of their AbstractDrawables primitives if constructor is called with parameters enabling sorting. The list of primitives is ordered using either the provided DefaultOrderingStrategy or an other specified AbstractOrderingStrategy. Sorting is usefull for handling transparency properly. The Graph maintains a reference to its mother Scene in order to inform the Views when its content has change and that repainting is required. The add() method allows adding a AbstractDrawable to the scene Graph and updates all views' viewpoint in order to target the center of the scene.

dispose

add

public void add(AbstractDrawable drawable,
                boolean updateViews)

Add a Drawable to the graph and call all views' so that they update their bounds according to their mode (automatic or manual). Addition is to the graph is synchronized.

Parameters:

drawable: - The drawable that must be added to the scene graph.

update: - should be true if you wish to have all the views updated with old bounds including drawable bounds

add

public void add(AbstractDrawable drawable)

add

public void add(List<? extends AbstractDrawable> drawables,
                boolean updateViews)

add

public void add(List<? extends AbstractDrawable> drawables)

remove

public boolean remove(AbstractDrawable drawable,
                      boolean updateViews)

Delete a Drawable from the SceneGraph and update all views' viewpoint in order to target the center of the scene.

Parameters:

drawable - The drawable that must be deleted from the scene graph.
