| AggregatingHashtable | | public class AggregatingHashtable extends Hashtable (Code) | | A hashtable that holds a list of values instead of a single value for one key.
In any case the get(Object) method returns a List (Vector) of values.
Every new put() call adds to the list of values. The remove()
call removes the whole list of values at once.
