SizeLimitCache<K extends Object, V extends Object> class

Cache with size limit (evict oldest). Roadmap #198.

Optional ttl expires entries after the given duration; expired entries are treated as missing on get. Implements Cache so it is swappable with the other eviction policies behind that interface.

Implemented types

• Cache<K, V>
