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

DummyGroupNode

public DummyGroupNode()

Method Detail

setParent

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.

Overrides:

setParent in class Node

ensureCapacity

protected boolean ensureCapacity(int minCapacity)

Overrides:

ensureCapacity in class GroupNode

addChild

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.

Overrides:

addChild in class GroupNode

setChild

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.

Overrides:

setChild in class GroupNode

Returns:

the Node, that previously lived at the given position

removeChild

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.

Overrides:

removeChild in class GroupNode

updateBounds

public void updateBounds(boolean onlyDirty)

Update bounds sets the bounds and virutal world bounds of all nodes recursively.

Overrides:

updateBounds in class GroupNode

Parameters:

onlyDirty - Only update those nodes which have been marked as dirty.

newInstance

protected DummyGroupNode newInstance()

Specified by:

newInstance in class GroupNode

Returns:

a new instance of this class. This is invoked by the sharedCopy() method.

See Also:

GroupNode.sharedCopy()

traverse

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

Parameters:

callback - the listener is notified of any traversed Node on the way

Returns:

if false, the whole traversal will stop
