b60c6ee2c8 Consistency. 2015-03-08 09:23:24 -04:00

f66ee0bbc6 Injected LRU capabilities that simply: 
* ensures that when an item is added, if the number of unexpired items
>= maximum number of items specified, the oldest (based on ACCESS) is
expired
* when an item is "gotten", or "set", the access time is updated

The existing janitor system is unchanged, and used to actually delete
the items.

The only change from a consumer standpoint, is one addition parameter at
the end of a "New" call, that specifies the maximum number of items to
allow, or 0, if you want to disable the LRU at all.

Patrick Mylund Nielsen
5388b25b3b Use an RWMutex instead of a Mutex, making Get a read operation only (this slightly changes the eviction behavior: lookup doesn't completely expunge an expired item, but the janitor still will at the next cleanup.) Also, use the same RWMutex in Load and Save (thanks, Alan Shreve) 2013-06-30 20:11:57 -04:00

72916cf4df Update README to reflect API change: IncrementFloat now only works on float32 and float64, and the use of Decrement should be encouraged over Increment (with a negative number) since Increment converting a negative signed integer to an unsigned integer probably isn't the intended behavior 2012-08-17 13:48:55 +02:00
