Map
------------------

print it.toString(); // prints “(begin)[(1 -> Query: query object 38824e0)]”
// Go on for as long as elements are found in the set...
while (it.more())
{
// fetch the next element
print it.key(); // prints 4 2 1
print it.value().toString(); // print something like Query object 3881270

Set
------------------

List
----------------------
