@Contract(threading=IMMUTABLE) public class HttpCacheEntry extends Object implements Serializable
HttpResponse in a cache.
Some entries can optionally depend on system resources that may require
explicit deallocation. In such a case getResource() should return
a non null instance of Resource that must be deallocated by calling
Resource.dispose() method when no longer used.| Constructor and Description |
