value_type of the range is comparable

[x,y] in the returned range, x==y is false.

and Forward Range.
#include <boost/range/adaptor/uniqued.hpp> #include <boost/range/algorithm/copy.hpp> #include <boost/assign.hpp> #include <algorithm> #include <iostream> #include <vector> void uniqued_example_test() { using namespace boost::assign; using namespace boost::adaptors; std::vector<int> input; input += 1,1,2,2,2,3,4,5,6; boost::copy( input | uniqued, std::ostream_iterator<int>(std::cout, ",")); }
This would produce the output:
1,2,3,4,5,6
