public class WalkedPath
extends ArrayList<LiteralPathElement>

DataStructure used by a SpecTransform during it's parallel tree walk. At any given point in time, it represents where in the tree walk a Spec is operating. It is primarily used to by the ShiftrLeafSpec and CardinalityLeafSpec as a reference to lookup real values for output "&(1,1)" references. It is expected that as the SpecTransform navigates down the tree, LiteralElements will be added and then removed when that subtree has been walked.
