[collections] Adding a TTL to LazyMap

           Summary: [collections] Adding a TTL to LazyMap
           Product: Commons
           Version: unspecified
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Enhancement

        ReportedBy: tobrien@discursive.com


Would it be beyond the scope of LazyMap to add a "time to live" to a LazyMap?

One could, optionally, decorate a Map with a Transformer and a long TTL value -
the LazyMap would maintain a Map of timestamps and calculate an age every time
an object was encountered by a get().  If an object's age exceeded the TTL, the
relevant Factory or Transformer would be invoked.
