public class DriverPanelCache
extends Object

A cache of the state of a DriverPanel. Used to restore a DriverPanel to a past state, to minimize re-typing for the user. Different DriverPanels can even use each other's cached values, whenever the cache keys match. For each DriverDialog, one DriverPanelCache is associated with one Layer.
