Interface CacheEntry<K,T>

All Known Subinterfaces:

MutableCacheEntry<K,T>

public interface CacheEntry<K,T>

Object representing a cache entry. With the cache entry it can be checked whether a mapping in the cache is present, even if the cache holds null or an exception.

After retrieved the entry instance does not change the values, even if the value for its key is updated in the cache.

Design remark: The cache is generally also aware of the time the object will be refreshed next or when it expired. This is not exposed to applications by intention.
