public class SwitchValueInterpolator
SwitchValueInterpolator behavior. This class defines a behavior that modifies the selected child of the target switch node by linearly interpolating between a pair of specified child index values (using the value generated by the specified Alpha object).

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 node references
by using the getNewObjectReference
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.
NOTE: Applications should not call this method directly. It should only be called by the cloneTree method.
