Is there a means to figure out what kinds of variables a Gee.List stores?
The following doesn't work because if I call mystery_list.get(0), I get
the compiler error: has no member named ‘g_destroy_func’.
using Gee;
public bool perform (Gee.List mystery_list) {
if (! mystery_list.is_empty) {
Value val = mystery_list.get (0);
if (val.type().is_value_type) {
// something something
}
}
}
If I cast mystery_list to Gee.List <Object>, my problem is solved (because
now a destructor is available), but then that means that mystery list
can only contain items descended from GObject.
You can workaround it by first knowing the subclass using type check, then
getting the property "g-type" which is automatically created by generics in
vala.
E.g.:
Type type;
if (list is LinkedList) list.get("g-type", out type);
You can temporarly look here for "hidden" properties:
