Detailed Description

template<typename Index_, typename Data_, typename Distance_, class AnnoyDistance_, typename AnnoyIndex_ = Index_, typename AnnoyData_ = float, class AnnoyRng_ = Annoy::Kiss64Random, class AnnoyThreadPolicy_ = Annoy::AnnoyIndexSingleThreadedBuildPolicy>
class knncolle_annoy::AnnoyPrebuilt< Index_, Data_, Distance_, AnnoyDistance_, AnnoyIndex_, AnnoyData_, AnnoyRng_, AnnoyThreadPolicy_ >

Prebuilt index for an Annoy search.

Instances of this class are usually constructed using AnnoyBuilder::build_raw().

Template Parameters

Index_	Integer type for the observation indices.
Data_	Numeric type for the input and query data.
Distance_	Floating-point type for the distances.
AnnoyDistance_	An Annoy-compatible class to compute the distance between vectors, e.g., Annoy::Euclidean, Annoy::Manhattan. Note that this is not the same as knncolle::DistanceMetric.
AnnoyIndex_	Integer type for the observation indices in the Annoy index.
AnnoyData_	Floating-point type for data in the Annoy index. This defaults to a float instead of a double to sacrifice some accuracy for performance.
AnnoyRng_	An Annoy class for random number generation.
AnnoyThreadPolicy_	An Annoy class for the threadedness of Annoy index building.
