So you could have a FilePathsForSaving and a AuthorContactDetails interface
that are both implemented by your configuration object. When you come to
use them you only need a subset of the configuration object. So you could
have a method:
void save_my_work (Work work_object, FilePathsForSaving my_big_configuration_object) {...}
So i have prepared two interface classes [1] and [2].
The advantage is that each method only needs a subset of the data and it means you can feed alternative objects in, so long as they implement the same interface. That could be useful for testing individual components of your application. So if you want to write a test of the save_my_work() command then you can feed in paths in a temporary directory and check the relevant data is saved without having to construct a whole configuration object, just the FilePathsForSaving.
In general i planned to just get the data from the interfaces, not to set it. The GSettings i would like to set with dconf, and the file pathes are fixed and don't need to change it.
you could have: public AuthorContactDetails author_contact_details; and then the AuthorContactDetails object has properties for the name, etc.
I have used it so [3]. As far as i understand, i get now the contents from both classes and the properties are connected with them. Or? What are the next steps. Should the Configuration object now inherit from AuthorDetails and FilePathes? Or should each new class, who needs stuff from a interface inherit from a interface like "public class New : AuthorDetails"?
