Question

The code is something like so

 void buildIt(Object& o, Tokenizer::const_iterator begin, Tokenizer::const_iterator end){
   if(begin == end) return;
   else{
    string parent = *begin;
    bool hasChild = (begin+1) != end; //error: class booost::token_iterator<...> has no member named 'advance'
   }
 }

How can I check to see if the next iterator is valid without moving it?

Answer 1

You can always just copy the iterator and increment the copy. Or use boost::next.

if(boost::next(iter) == end)
  cout << "...";
