Created:apr 2010
Notes:DEPRECATED: Uses the MapBackedCollection which used a temp-table
to store the name-value pairs. Instead, use another ISet class
such as OE.Core.Collections.Set.
No empty constructor, specialized for KeySet of IMap
- Changes to the map are reflected here, and vice-versa.
- Supports removal and removes the corresponding map entry from the map
(Iterator.remove, Collection.remove, removeAll, retainAll and clear) .
- Do not support add and addAll.
- no empty constructor, specialised for IMap
