Deserializing an abstract class?

Question

Delphi

Greetings.
There is a set of Delphi XE2 classes:

TBaseAbstractClass = class abstract
  name : string;
end;

TDerivedClassStr = class(TBaseAbstractClass)
  value : string;
end;

TDerivedClassFloat = class(TBaseAbstractClass)
  value : float;
end;

TMyObject = class
    objs : array of TBaseAbstractClass;
end;

There is JSON:

{
 [
    {"name" : "name1", "value" : "value1"},
    {"name" : "name1", "value" : "value2"}
 ]
}

It can be deserialized as TMyObject, but then the values ​​are lost, and typecasting causes an error (which is not at all obvious to me).
Deserialization is done by the superobject library .
Is there a way to store the value value, but in a way that does not create:

TMyObject = class
    objs : array of TDerivedClassStr;
end;

Answer 1

Didn't use superobject, but how does he guess what type of class needs to be deserialized? It's not obvious from your JSON. You need to store the class name in an array when serializing and when deserializing create them using RTTI.
