public class TwoKeyTable
extends Object
implements Serializable
Manages many-to-many relationship between to types of keys (key1 and key2 objects). A number of key2 objects can be stored under a key1 objects. A given key2 object can be stored under several key1 obects. This class manages that relationsip and provides easy access to information stored under either key1 or key2 objects.
