Detailed Description

template<class T, class DataSource, typename _DistanceType = T, typename IndexType = uint32_t>
struct nanoflann::L1_Adaptor< T, DataSource, _DistanceType, IndexType >

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)
DataSourceSource of the data, i.e. where the vectors are stored
_DistanceTypeType of distance variables (must be signed)
IndexTypeType of the arguments with which the data can be accessed (e.g. float, double, int64_t, T*)
