Detailed Description

template<typename PointInT, typename OutT>
struct pcl::CopyIfFieldExists< PointInT, OutT >

A helper functor that can copy a specific value if the given field exists.

Note

In order to actually copy the value an instance of this functor should be passed to a pcl::for_each_type loop. See the example below.

PointInT p;
bool exists;
float value;
typedef typename pcl::traits::fieldList<PointInT>::type FieldList;
pcl::for_each_type<FieldList> (pcl::CopyIfFieldExists<PointT, float> (p, "intensity", exists, value));
