Hello, i want to parse the objects of a class in a txt file. I want to build the method in the class write_in_file but i don t want to parse only the variables of the class but the specific form of the method showClass(showIstorikoAsthenous). Also i want to have access to the variables so i can read all the variables separately. How can i accomplish with that???

the following code is the class istorikoAsthenous:
