Struct faiss::simd_result_handlers::RangeHandler
-
template<class C, bool with_id_map = false>
struct RangeHandler : public faiss::simd_result_handlers::ResultHandlerCompare<C, false> Result hanlder for range search. The difficulty is that the range distances have to be scaled using the scaler.
Public Types
-
using T = typename C::T
-
using TI = typename C::TI
-
using RHC = ResultHandlerCompare<C, with_id_map>
Public Functions
-
inline RangeHandler(RangeSearchResult &rres, float radius, size_t ntotal, const IDSelector *sel_in)
-
inline virtual void begin(const float *norms) override
-
inline virtual void handle(size_t q, size_t b, simd16uint16 d0, simd16uint16 d1) final
called when 32 distances are computed and provided in two simd16uint16. (q, b) indicate which entry it is in the block.
-
inline virtual void end() override
-
inline virtual void set_block_origin(size_t i0_in, size_t j0_in) final
set the sub-matrix that is being computed
-
inline void adjust_with_origin(size_t &q, simd16uint16 &d0, simd16uint16 &d1)
-
inline int64_t adjust_id(size_t b, size_t j)
-
inline uint32_t get_lt_mask(uint16_t thr, size_t b, simd16uint16 d0, simd16uint16 d1)
return binary mask of elements below thr in (d0, d1) inverse_test returns elements above
