Thomas Neidhart updated COLLECTIONS-347:
----------------------------------------
Fix Version/s: 4.x
> [contribution] LimitedSizeFifoMap
> ---------------------------------
>
> Key: COLLECTIONS-347
> URL: https://issues.apache.org/jira/browse/COLLECTIONS-347
> Project: Commons Collections
> Issue Type: New Feature
> Components: Map
> Reporter: Michael Thomas
> Priority: Minor
> Fix For: 4.x
>
> Attachments: LimitedSizeFifoMap.patch, LimitedSizeFifoMap.patch
>
>
> The {{LimitedSizeFifoMap}} never exceeds a given element limit by deleting
> old entries, whenever new ones are inserted. It may be of use for caches
> holding memory-intense objects (it is for me, anyway).
> The patch contains:
> * the interface {{LimitedSizeMap}}
> * the fully documented implementation {{LimitedSizeFifoMap}}, which deletes
> the oldest items first
> * the accompanying unit test
> If you find anything that needs improvement, please let me know.
