Sort Vector of objects in Scala

How can I sort a Vector of my objects in Scala? Is there some library sorting routines or do I have to write my own?

I have a class:

class Data2D(var x:Int, var y:Int)

and I am passing a vector of these to my function:

private def foo(data: Vector[Data2D]): Int = {
     data:Vector sortedOnX = // ??
}

how can I sort the vector, based on the x-values of the Data2D objects?

In java I do:

Collections.sort(data, XComparator.INSTANCE);

where XComparator is:

enum XComparator implements Comparator<Data2D> {
    INSTANCE;
    @Override
    public int compare(Data2D o1, Data2D o2) {
        if (o1.getX() <= o2.getX()) {
            return -1;
        } else {
            return 1;
        }
    }
}
