Detailed Description

template<class T, class DataSource, typename _DistanceType = T>
struct nanoflann::L1_Adaptor< T, DataSource, _DistanceType >

Manhattan distance functor (generic version, optimized for high-dimensionality data sets). Corresponding distance traits: nanoflann::metric_L1

Template Parameters
TType of the elements (e.g. double, float, uint8_t)
_DistanceTypeType of distance variables (must be signed) (e.g. float, double, int64_t)
