        public AsynchronousAsyncValidator​(CachingHttpAsyncClient cachingClient,
                                  org.apache.http.impl.client.cache.CacheConfig config)
        Create AsynchronousValidator which will make revalidation requests using the supplied CachingHttpAsyncClient, and a ThreadPoolExecutor generated according to the thread pool settings provided in the given CacheConfig.
        Parameters:
        cachingClient - used to execute asynchronous requests
        config - specifies thread pool settings. See CacheConfig.getAsynchronousWorkersMax(), CacheConfig.getAsynchronousWorkersCore(), CacheConfig.getAsynchronousWorkerIdleLifetimeSecs(), and CacheConfig.getRevalidationQueueSize().

        AsynchronousAsyncValidator​(CachingHttpAsyncClient cachingClient,
                           java.util.concurrent.ExecutorService executor)
        Create AsynchronousValidator which will make revalidation requests using the supplied CachingHttpAsyncClient and ExecutorService.
        Parameters:
        cachingClient - used to execute asynchronous requests
        executor - used to manage a thread pool of revalidation workers

      • revalidateCacheEntry

        public void revalidateCacheEntry​(org.apache.http.HttpHost target,
                                 org.apache.http.client.methods.HttpRequestWrapper request,

                                 org.apache.http.client.cache.HttpCacheEntry entry)
        Schedules an asynchronous revalidation

      • markComplete

        void markComplete​(java.lang.String identifier)
        Removes an identifier from the internal list of revalidation jobs in progress. This is meant to be called by AsynchronousValidationRequest.run() once the revalidation is complete, using the identifier passed in during constructions.
