Detailed Description

template<class T, class DataSource, typename _DistanceType = T>
struct nanoflann::L2_Adaptor< T, DataSource, _DistanceType >

Squared Euclidean distance functor (generic version, optimized for high-dimensionality data sets). Corresponding distance traits: nanoflann::metric_L2

Template Parameters

T	Type of the elements (e.g. double, float, uint8_t)
DistanceType	Type of distance variables (must be signed) (e.g. float, double, int64_t)
