[Boost-users] boost::indirect_iterator

Consider this code:

vector<int> coll;
// ... push back some values
vector<int*> ptrcoll;
// ... push back pointers to the values of coll

indirect_iterator< vector<int*>::iterator > begin(ptrcoll.begin()), 
end(ptrcoll.end());

sort( begin, end, less<int> );

My question: After the sort statement, coll is sorted, right? (and 
ptrcoll is not). However, I need to sort a vector of pointers according 
to a predicate which applies to non-pointers. In this case, I want to 
sort ptrcoll, according to the less-relation on the pointees in coll.
How can I achieve that?
