If the specified offset is beyond the beginning (or end) of the collection, the iterator is
positioned at the beginning (or end) of the collection.
Example
The following example positions the current iterator at the first item in the collection, moves
to the next-to-last item, and performs a calculation on a field belonging to that item:
my_ds.addItem({name:"Billy", id:104, gradeLevel:4});
my_ds.addItem({name:"Carrie", id:106, gradeLevel:4});
my_ds.addItem({name:"Mally", id:112, gradeLevel:3});
my_ds.addItem({name:"Cathy", id:110, gradeLevel:4});
my_ds.addItem({name:"Bobby", id:105, gradeLevel:4});
my_ds.first();
var itemsToSkip:Number = 3;
trace(my_ds.currentItem.name); // Billy
my_ds.skip(itemsToSkip);
trace(my_ds.currentItem.name); // Mally
