Filtered Maps, Lists, and Sets

           Summary: Filtered Maps, Lists, and Sets
           Product: Commons
           Version: 3.1
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Enhancement
          Priority: Other
         Component: Collections
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: comfortably007numb-python@yahoo.com


In the project I work I have found that it would be efficient (at a small cost
of memory) to use filtered maps, lists, and sets instead of creating a new copy
of the decorated entities that contains only the filtered elements.

To begin with I have implemented a FilteredMap and plan to implement
FilteredList and FilteredSet.  I will post the code for these in a couple of
days and it would be great if Collections library could accept these contributions.
