A resource effective cache implementation where any entry's lifetime is kept track of separately and evicted when it's time-to-live reaches zero. Ideal for storing objects where lifetime differs per object such as tokens.
Import it
compile group: 'com.bisnode.cache', name: 'ttl-cache', version: '1.0.3'
Use it
// Instantiate a new cache where both keys and values are of type String
// and object lifetime will be measured in seconds
TTLCache<String, String> cache = new TimedKeyValueCache<>(TimeUnit.SECONDS);
// Adding an item to the cache with automatic eviction after 60 seconds
cache.add("my key", "my value", 60);
// Retrieving an item from the cache (if it's in there)
Optional<String> valueInCache = cache.get("my key");Copyright 2018 Bisnode
