To handle these ambiguities, a callback mechanism is provided A leaf node that needs to update referenced nodes upon being duplicated by a call to cloneTree must implement the updateNodeReferences method By using this method, the cloned leaf node can determine if any nodes referenced by it have been duplicated and, if so, update the appropriate references to their cloned counterparts Suppose, for instance, that the leaf node Lf1 in Figure 6-3 implemented the updateNodeReferences method Once all nodes had been duplicated, the cloneTree method would then call each cloned leaf s node updateNodeReferences method When cloned leaf node Lf2 s method was called, Lf2 could ask if the node N1 had been duplicated during the cloneTree operation If the node had been duplicated, leaf Lf2 could then update its internal state with the cloned node, N2 (see Figure 6-4)

This Leaf node method is called by the cloneTree method after all nodes in the subgraph have been cloned The user can query the NodeReferenceTable object (see Section 625, NodeReferenceTable Object ) to determine if any nodes that the leaf node references have been duplicated by the cloneTree call and, if so, what the corresponding node is in the new subgraph If a user extends a prede ned Java 3D object and adds a reference to another node, this method must be de ned in order to ensure proper operation of the cloneTree method The rst statement in the user s updateNodeReferences method must be superupdateNodeReferences(referenceTable) For prede ned Java 3D nodes, this method will be implemented automatically The NodeReferenceTable object is passed to the updateNodeReferences method and allows references from the old subgraph to be translated into refer-ences in the cloned subgraph The translation is performed by the getNewNodeReference method

Dangling References
public final SceneGraphObject getNewObjectReference(SceneGraphObject oldReference)
This method takes a reference to the node in the original subgraph as an input parameter and returns a reference to the equivalent node in the just-cloned subgraph If the equivalent node in the cloned subgraph does not exist, either an exception is thrown or a reference to the original node is returned (see Section 623, Dangling References )
Dangling References
Because cloneTree is able to start the cloning operation from any node, there is a potential for creating dangling references A dangling reference can occur only when a leaf node that contains a reference to another scene graph node is cloned If the referenced node is not cloned, a dangling reference situation exists: There are now two leaf nodes that access the same node (Figure 6-5) A dangling reference is discovered when a leaf node s updateNodeReferences method calls the getNewNodeReference method and the cloned subgraph does not contain a counterpart to the node being looked up

Dangling Reference: Bold Nodes Are Being Cloned
When a dangling reference is discovered, cloneTree can handle it in one of two ways If cloneTree is called without the allowDanglingReferences parameter set to true, a dangling reference will result in a DanglingReferenceException being thrown The user can catch this exception if desired If cloneTree is called with the allowDanglingReferences parameter set to true, the updateNodeReferences method will return a reference to the same object passed into
