Class Appearance

java.lang.Object

de.jreality.scene.SceneGraphNode

de.jreality.scene.Appearance

Direct Known Subclasses:

MirrorAppearance

public class Appearance
extends SceneGraphNode

The appearance node. Contains attributes of arbitrary type stored as (key,value) pairs in a HashMap. There are special methods for setting attributes whose values are common built-in types: double, float,int, boolean,and char.

You can query the state of the Appearance by using getAttribute(String). If not attribute has been defined for this key, the special object INHERITED is returned.

If you wish to remove an attribute value from the key foo, call

 setAttribute(foo, Appearance.INHERITED);
 

Some wiser person will have to tell you when the special object DEFAULT is returned.

TODO: fire ONE single event that reports all changed attributes
