List Sample

A dynamic length ArrayList

using Gee;

void main () {
    var list = new ArrayList<int> ();
    list.add (1);
    list.add (2);
    list.add (5);
    list.add (4);
    list.insert (2, 3);
    list.remove_at (3);
    foreach (int i in list) {
        stdout.printf ("%d\n", i);
    }
    list[2] = 10;                       // same as list.set (2, 10)
    stdout.printf ("%d\n", list[2]);    // same as list.get (2)
}

Compile and Run

valac --pkg gee-0.8 gee-list.vala
./gee-list

You can use any type fitting into the size of a pointer (e.g. int, bool, reference types) directly as generic type argument: bool, int, string, MyObject. Other types must be "boxed" by appending a question mark: float?, double?, MyStruct?. The compiler will tell you this if necessary.
