Module Ocsigen_cache

Cache. Association tables (from any kind of database) that keep the most recently used values in memory. It is also possible to set a maximum lifetime for data in the cache.

It is based on a structure of doubly linked lists with maximum size, that keeps only the mostly recently used values first, if you call the up function each time you use a value. (Insertion, remove and "up" in time 1). This structure is exported, so that it can be used in other cases.

Not (preemptive) thread safe.
