core.memoize v0.5.5 Release Notes

core.memoize is a Clojure contrib library providing the following features:

• An underlying PluggableMemoization protocol that allows the use of customizable and swappable memoization caches that adhere to the synchronous CacheProtocol found in core.cache

• Memoization builders for implementations of common caching strategies, including:

  • First-in-first-out (clojure.core.memoize/fifo)
  • Least-recently-used (clojure.core.memoize/lru)
  • Least-used (clojure.core.memoize/lu)
  • Time-to-live (clojure.core.memoize/ttl)
  • Naive cache (memo) that duplicates the functionality of Clojure's memoize function

• Functions for manipulating the memoization cache of core.memoize backed functions
