Subject [jira] Updated: (COLLECTIONS-347) [contribution] LimitedSizeFifoMap
Date Mon, 21 Dec 2009 18:57:18 GMT

     [ https://issues.apache.org/jira/browse/COLLECTIONS-347?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Michael Thomas updated COLLECTIONS-347:
---------------------------------------

    Description: 
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.
