It is quite simple to do it, you write the object down to file, then you read it:

My questions are

  1. why when we put [RemoteClass(alias=”foo.Bar”)] into VO, it can be
    cast automatically (otherwise the type of the deserialized object is
    Generic Object with correct properties data inside it)?
  2. Is there another way to achieve it without RemoteClass tag? (Using metadata tag is preference)

Thanks

    1. The answer is in the page you linked to:

      Note that the alias is a key that is stored with the class instance
      and links the class definition with the specific object that is stored
      in the ByteArray when an instance of that object is serialized. This
      key can be any unique string identifying this class, but convention is
      to use the fully normalized package and class name.

      That’s why you get a generic object if you omit the alias – the deserialization method does not know what to do with the data, unless you specify to which class the values should be mapped.

    2. Yes, there is: registerClassAlias() does the same thing. But the metadata tag is much prettier to read 😉
