---------------------------------------------
Missing a patch.
> Request for UnBoundedLRUMap implementation with extra get method
> ----------------------------------------------------------------
>
> Key: COLLECTIONS-395
> URL: https://issues.apache.org/jira/browse/COLLECTIONS-395
> Project: Commons Collections
> Issue Type: Wish
> Components: Map
> Affects Versions: Nightly Builds
> Reporter: David Hawthorne
> Priority: Minor
>
> I've created an UnBoundedLRUMap implementation (based off of BoundedLRUMap)
> using the svn tree at version 3.3, and this has come in so handy that it
> makes sense to suggest it to the masters in charge of the collections
> framework.
> One tweak I made to the copy we're using is an extra get method that takes
> two arguments: key and boolean. The boolean determines whether or not the
> MRU item is updated, so we can make requests into the map that do *not*
> affect order. This is sometimes necessary in real world environments where
> you do not want a data structure with LRU-only accesses.
> This implementation would solve the main problem we have with using the jdk's
> LinkedHashMap LRU implementation.
