Sorting an ArrayCollection

public function sortCollection(arrayCollection : ArrayCollection) : void
{
    //Create the sort field
    var dataSortField:SortField = new SortField();

    //name of the field of the object on which you wish to sort the Collection
    dataSortField.name = "name";
    dataSortField.caseInsensitive = true;
    
    /*
    If you wish to perform numeric sort then set:
    dataSortField.numeric = true;
    */
   
    //create the sort object
    var dataSort:Sort = new Sort();
    dataSort.fields = [dataSortField];
 
    arrayCollection.sort = dataSort;
    //refresh the collection to sort
    arrayCollection.refresh();
