Set Sample

Sets are unordered and do not contain duplicate elements.

using Gee;

void main () {
    var my_set = new HashSet<string> ();
    my_set.add ("one");
    my_set.add ("two");
    my_set.add ("three");
    my_set.add ("two");         // will not be added because it's a duplicate
    foreach (string s in my_set) {
        stdout.printf ("%s\n", s);
    }
}
