      • serialize

        public byte[] serialize​(HttpCacheStorageEntry storageEntry)
                 throws ResourceIOException
        Serializes an HttpCacheStorageEntry object into a byte array using an HTTP-like format.

        The metadata is encoded into HTTP pseudo-headers for storage.

        Specified by:
