TransparencyInterpolator behavior. This class defines a behavior that modifies the transparency of its target TransparencyAttributes object by linearly interpolating between a pair of specified transparency values (using the value generated by the specified Alpha object).

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

, causes the
duplicateOnCloneTree
flag to be ignored. When
false

.
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 node references
by using the getNewNodeReference
method found in the
NodeReferenceTable
object. If a match is found, a
reference to the corresponding Node 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
node is returned depending on the value of the
allowDanglingReferences
parameter passed in the
cloneTree
call.referenceTable
- a NodeReferenceTableObject that contains the
getNewNodeReference
method needed to search for
new object instances.NodeReferenceTable
