public class DummyGroupNode
extends GroupNode

The DummyGroupNode is meant to be used, if Nodes must be grouped even if they are already in other Groups. PickingLibrary accepts instances of DummyGroupNode.

Constructor Detail


public DummyGroupNode()
Method Detail


public void setParent(GroupNode parent)
Description copied from class: Node
Sets the parent for this Node object. If the parent is live then this node and any children it has are made live. If the parent is null then this node and any children it has are made not live.

setParent in class Node


protected boolean ensureCapacity(int minCapacity)
ensureCapacity in class GroupNode


public void addChild(Node child,
                     int index)
Insert a child at the specified index. The parent of the child is set to this object. If this object is live then the child is set live.

addChild in class GroupNode


public Node setChild(Node child,
                     int index)
Set the child at the specified index. If an existing child is at that location then it is removed, its parent is set to null and it is set not live. If this object is live then the child is set live.

setChild in class GroupNode
the Node, that previously lived at the given position


public Node removeChild(int index)
Remove the child at the specified index. The parent of the child is set to null. The child is made not live.

removeChild in class GroupNode


public void updateBounds(boolean onlyDirty)
Update bounds sets the bounds and virutal world bounds of all nodes recursively.

updateBounds in class GroupNode
onlyDirty - Only update those nodes which have been marked as dirty.


protected DummyGroupNode newInstance()
Specified by:
newInstance in class GroupNode
a new instance of this class. This is invoked by the sharedCopy() method.
See Also:


public boolean traverse(DetailedTraversalCallback callback)
Description copied from class: Node
Traverses the scenegraph from this node on. If this Node is a Group it will recusively run through each child.

Specified by:
traverse in class Node
callback - the listener is notified of any traversed Node on the way
if false, the whole traversal will stop
