Detailed Description

Static helper class to generate vector data for all supported data types.

This class uses the default seed for generation to ensure repeatable results as long as parameters for the tests are the same.

Member Function Documentation

generateRandomIntersectionIndicesU()

std::vector< std::uint64_t > hebench::TestHarness::DataGeneratorHelper::generateRandomIntersectionIndicesU ( std::uint64_t  elem_count, std::uint64_t  indices_count = 0  )

static

Generates uniform random amount of indices.

Parameters

[in]	elem_count	Number of elements in the set.
[in]	indices_count	Number of pre-defined indices to be generated.

Returns

A vector holding the indices.
