Class DefaultQueueableCacheStorage

java.lang.Object
  org.fusesource.restygwt.client.cache.DefaultQueueableCacheStorage

All Implemented Interfaces:

CacheStorage<Response>, QueueableCacheStorage

Direct Known Subclasses:

VolatileQueueableCacheStorage

public class DefaultQueueableCacheStorage
extends Object
implements QueueableCacheStorage

this implementation stores Response objects until they are removed or purged. when retrieved from the cache the Response will have an extra header field "X-Resty-Cache". this allows CallbackFilter to determine the action on whether the Response came from the cache or just came over the wire.
