de.jreality.scene.Scene

public class Scene
extends Object

A utility class providing static methods for applying a set of changes simultaneously to an element of the scene graph. It minimizes the amount of locking that is required to do this.

Method Detail

executeReader

public static void executeReader(SceneGraphNode toRead,
                                 Runnable reader)

Perform a piece of code to query a SceneGraphNode in a read-locked state of the node. The code is encapsulated in a Runnable and can safely assume that different query methods on that node return valid values representing the same unmodified state.

executeReader

public static void executeReader(Collection toRead,
                                 Runnable reader)

Not implemented yet.

executeWriter

public static void executeWriter(SceneGraphNode toWriteIn,
                                 Runnable writer)

Perform a piece of code to manipulate a SceneGraphNode in a write-locked state of the node. The code is encapsulated in a Runnable and no other code can get a read-lock while it's run method is being executed. So no-one will read an in-between state.
