Detailed Description

template<typename Index_, typename Data_, typename Distance_, class DistanceMetric_>
class knncolle::BruteforcePrebuilt< Index_, Data_, Distance_, DistanceMetric_ >

Index for a brute-force nearest neighbor search.

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

Template Parameters

Index_	Integer type for the indices.
Data_	Numeric type for the input and query data.
Distance_	Floating point type for the distances.
DistanceMetric_	Class implementing the distance metric calculation. This should satisfy the DistanceMetric interface.
