The Clip leaf node defines the back, or far, clip distance in the virtual universe. The distance is specified in the local coordinate system of this node. The front clip distance is defined in the View object. If no clip node is in scope of the view platform associated with the current view, then the back clip distance is also defined by the View.

into
the current node. This method is called from the
cloneNode
method which is, in turn, called by the
cloneTree
method.
For any NodeComponent objects
contained by the object being duplicated, each NodeComponent
object's duplicateOnCloneTree
value is used to determine
whether the NodeComponent should be duplicated in the new node
or if just a reference to the current node should be placed in the
new node. This flag can be overridden by setting the
forceDuplicate
parameter in the cloneTree
method to true
.
originalNode
- the original node to duplicate.forceDuplicate
- when set to true
, causes the
duplicateOnCloneTree
flag to be ignored. When
false
, the value of each node's
duplicateOnCloneTree
variable determines whether
NodeComponent data is duplicated or copied.Node.cloneTree()

public void updateNodeReferences(NodeReferenceTable referenceTable)
cloneTree
.
This method is called by cloneTree
after all nodes in
the sub-graph have been duplicated. The cloned Leaf node's method
will be called and the Leaf node can then look up any object references
by using the getNewObjectReference
method found in the
NodeReferenceTable
object. If a match is found, a
reference to the corresponding object in the newly cloned sub-graph
is returned. If no corresponding reference is found, either a
DanglingReferenceException is thrown or a reference to the original
object is returned depending on the value of the
allowDanglingReferences
parameter passed in the
cloneTree
call.referenceTable
- a NodeReferenceTableObject that contains the
getNewObjectReference
method needed to search for
new object instances.NodeReferenceTable
