Detailed Description

Compile-time interface for matrix data.

This defines the expectations for a matrix of observation-level data to be used in Builder::build_raw(). Each matrix should support extraction of the vector of coordinates for each observation.

Member Typedef Documentation

data_type

typedef double knncolle::MockMatrix::data_type

Type of the data. Any floating-point type may be used here.

dimension_type

typedef int knncolle::MockMatrix::dimension_type

Integer type for the dimension indices. Any integer type may be used here.

index_type

typedef int knncolle::MockMatrix::index_type

Type for the observation indices. Any integer type may be used here.

Member Function Documentation

create_workspace()

Workspace knncolle::MockMatrix::create_workspace ( ) const

inline

Returns

A new consecutive-access workspace, to be passed to get_observation().

get_observation()

const data_type * knncolle::MockMatrix::get_observation ( Workspace &  workspace ) const

inline

Parameters

workspace

Workspace for consecutive access.

Returns

Pointer to an array of length equal to num_dimensions(), containing the coordinates for the next observation.

For a newly created Workspace, the first call to get_observation() should return the coordinates of the first observation in the dataset; the next call should return the coordinates of the second observation; and so on, for up to num_observations() calls, after which the Workspace should no longer be used.

num_dimensions()

dimension_type knncolle::MockMatrix::num_dimensions ( ) const

inline

Returns

Number of dimensions.

num_observations()

index_type knncolle::MockMatrix::num_observations ( ) const

inline

Returns

Number of observations.
