Partly. This is an 'object' and not a list of objects. But I
understand correctly that it is not possible to define real objects?
What I would like is something like (C++ code):

class Object {
    String type;
    String description;
    String functionname;
    String displayString;

std::vector <Object> objectVector;

When given a certain type I then need to retreive the 'object' from
the list to use.
