I have this:
typedef LegacySequentialContainer<string> LegacyStringVector;
LegacyStringVector lsv;
// ... filling lsv with strings ...
I realized this:
boost::counting_iterator<int> it(0); boost::counting_iterator<int> end(lsv.length()); while (it < end) cout << boost::bind(&LegacyStringVector::operator[], lsv, _1)(*it++) << " "; cout << "\n";
and it works. However, I wish to do the same but using std::copy or std::for_each instead.
I tried the following but none is able to compile:
copy(boost::counting_iterator<int>(0), boost::counting_iterator<int>(lsv.size()), boost::bind(ostream_iterator<string>(cout, " "), &vector<string>::operator[], lsv, _1));
std::copy doesn't take a function object as it third argument, just an iterator. Try std::transform: std::transform( boost::counting_iterator<int>(0), boost::counting_iterator<int>(lsv.size()), ostream_iterator<string>(cout, " "), boost::bind( &LegacyStringVector::operator[], lsv, _1) );
