    • 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:
      serialize in interface HttpCacheEntrySerializer<byte[]>
      Parameters:
      storageEntry - the HttpCacheStorageEntry to serialize.
      Returns:
      the byte array containing the serialized HttpCacheStorageEntry.
      Throws:
      ResourceIOException - if there is an error during serialization.

    • deserialize

      public HttpCacheStorageEntry deserialize(byte[] serializedObject) throws ResourceIOException
      Deserializes a byte array representation of an HTTP cache storage entry into an instance of HttpCacheStorageEntry.
      Specified by:
      deserialize in interface HttpCacheEntrySerializer<byte[]>
      Parameters:
      serializedObject - the byte array representation of the HTTP cache storage entry
      Returns:
      the deserialized HTTP cache storage entry
      Throws:
      ResourceIOException - if an error occurs during deserialization
