## Inherits from

boost::put_get_helper< std::iterator_traits< T * >::reference, Dereference_property_map< T, T * > >.

## Definition

template<typename T, typename Iter = T*>
struct CGAL::Dereference_property_map< T, Iter >

Property map that converts a `T*` pointer (or in general an iterator over `T` elements) to the `T` object.

Is model of
  `LvaluePropertyMap`
