I wanted to know if it was possible to have an iterator behaving like both an indirect_iterator and a filter_iterator. I've tried to without success.

Here is a minimal code that compiles but crashes. ===================================== class CTest {

public: CTest(int Value,int Id) : value(Value),id(Id) {}; int id; int value;

};

std::vector<CTest*> vec; vec.push_back(new CTest(4,7)); vec.push_back(new CTest(4,1));

//I want an iterator that I could use like iter->id / iter->value and not (*iter)->id / (*iter)->value

struct SPredicate { bool operator()( C& x) { return (-1 < x.id); } };

typedef boost::filter_iterator<SPredicate, CTest*> FilterIterator;

Try boost::filter_iterator<SPredicate, boost::indirect_iterator<std::vector<CTest*>::const_iterator> >.

FilteredIterator end(*vec.end());

for(FilteredIterator iter(*vec.begin());start != end; iter++){ std::cout << "id" << iter->id << "\tValue" << iter->m << std::endl; } =====================================

I'm new to boost and is very impressed by its possibilites. Hope I can understand the code better later.
