SimpleLruCache

final class SimpleLruCache[V] extends Cache[V]

A thread-safe implementation of spray.caching.cache. The cache has a defined maximum number of entries it can store. After the maximum capacity is reached new entries cause old ones to be evicted in a last-recently-used manner, i.e. the entries that haven't been accessed for the longest time are evicted first.
