[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
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 marker interface {{LimitedSizeMap}}
* the fully documented implementation {{LimitedSizeFifoMap}}, which deletes
oldest items first
* the accompanying unit test
If you find anything that needs improvement, please let me know.
