\ccDefinition
  
The function \ccRefName\ computes if a polygon is convex.

\ccInclude{CGAL/Polygon_2_algorithms.h}

\ccGlobalFunction{template <class ForwardIterator, class Traits>
bool is_convex_2(ForwardIterator first, ForwardIterator last,
const Traits& traits); }
{
}


\ccHeading{Requirements}
\ccIndexSubitem[C]{bottom_vertex_2}{requirements}
\begin{enumerate}
    \item \ccc{Traits} is a model of the concept 
	  PolygonTraits\_2\ccIndexMainItem[c]{PolygonTraits_2}.
	  Only the following members of this traits class are used:
          \begin{itemize}
            \item \ccc{Less_xy_2}
            \item \ccc{Orientation_2}
            \item \ccc{less_xy_2_object}
            \item \ccc{orientation_2_object}
          \end{itemize}
    \item \ccc{ForwardIterator::value_type} should be \ccc{Traits::Point_2},
\end{enumerate}
