Interface JvmCache<K,V>

Type Parameters:

K - the key type

V - the value type

All Superinterfaces:

LocalCacheOperations<K,V>, VCache

@PublicApi
public interface JvmCache<K,V>
extends VCache, LocalCacheOperations<K,V>

Interface that defines the JVM cache operations.

Notes:

• null keys and values are NOT supported
• keys and values are stored by reference

Notes

• A cache has an associated time-to-live (ttl), which is expressed as Duration. The implementations may round-up the supplied ttl to the nearest second. E.g. 500 milliseconds may be converted to 1 second.
• Do not assume that the associated ttl defines exactly when entries are evicted. The implementation is free to choose how the ttl is interpreted. It may expire entries in a timely manner, or it may be delayed until next interaction with the cache.
