The current version of HashMap supports get/setComparator(), which can be used to enforce key ordering.

Hi to all,
one time the HashMap implementation will be "stable", what do you
think on adding also a LinkedHashMap implementation (an HashMap that
it's usable also as a LinkedList), like in standard Collections ?
It has a little overhead but in many cases it's useful.

For the moment, thanks for the current work.

Sandro
