Detailed Description

template<typename PointOutT, typename InT>
struct pcl::SetIfFieldExists< PointOutT, InT >

A helper functor that can set a specific value in a field if the field exists.

Note
In order to actually set the value an instance of this functor should be passed to a pcl::for_each_type loop. See the example below.
using FieldList = typename pcl::traits::fieldList<PointT>::type;
pcl::for_each_type<FieldList> (pcl::SetIfFieldExists<PointT, float> (p, "intensity", 42.0f));
