Properties are handled through a variadic list of property handlers. A PropertyHandler
can either be:
std::pair<PropertyMap, PLY_property<T> >
if the user wants to read a PLY property as a scalar value T (for example, storing an int
PLY property into an int
variable).std::tuple<PropertyMap, Constructor, PLY_property<T>...>
if the user wants to use one or several PLY properties to construct a complex object (for example, storing 3 uchar
PLY properties into a Color object that can for example be a CGAL::cpp11::array<unsigned char, 3>
). In that case, the second element of the tuple should be a functor that constructs the value type of PropertyMap
from N objects of types T
.OutputIteratorValueType | type of objects that can be put in OutputIterator . It is default to value_type_traits<OutputIterator>::type and can be omitted when the default is fine. |
OutputIterator | iterator over output points. |

Properties are handled through a variadic list of property handlers. A PropertyHandler

variable as an int
PLY property).std::tuple<PropertyMap, PLY_property<T>...>
if the user wants to write a complex object as several PLY properties. In that case, a specialization of Output_rep
must be provided for PropertyMap::value_type
