Constructor Detail

MultipassViewportLayer

public MultipassViewportLayer()
Construct a new layer instance

Method Detail

setUpdateHandler

protected void setUpdateHandler(NodeUpdateHandler handler)
Set the scenegraph update handler for this node. It will notify all its children of the value. A null value will clear the current handler.

Overrides:
setUpdateHandler in class SceneGraphObject
Parameters:
handler - The instance to use as a handler

setLive

protected void setLive(boolean state)
Notification that this object is live now. Overridden to make sure that the live state of the nodes represents the same state as the parent scene graph.

Overrides:
setLive in class SceneGraphObject
Parameters:
state - true if this should be marked as live now

setScene

public void setScene(MultipassScene sc)
              throws InvalidWriteTimingException,
                     AlreadyParentedException
Set a new scene instance to be used by this layer.

Note that a scene cannot have more than one parent, so sharing it between layers will result in an error.

Parameters:
sc - The scene instance to use, or null to clear
Throws:
InvalidWriteTimingException - An attempt was made to write outside of the NodeUpdateListener callback method
AlreadyParentedException - This scene already has a current parent preventing it from being used

getScene

public MultipassScene getScene()
Get the currently set scene instance. If no scene is set, null is returned.

Returns:
The current scene instance or null
