Functions
std::vector< std::size_t >	binSequence (std::array< std::size_t, 2u > minMaxBins, std::size_t expand, std::size_t nBins, Acts::detail::AxisBoundaryType type)
	Helper method to generate completely populated bin sequences that respect the boundary type of the axis.
template<typename grid_type >
std::set< typename grid_type::index_t >	localIndices (const grid_type &grid, const std::vector< typename grid_type::point_t > &queries, const std::vector< std::size_t > &expansion={})
	Helper method to fill local bins given a set of query points bin in between the extra points are filled, and a possible expansion of the bin window can be chosen.

std::string	outputIndices (const std::set< local_bin > &lbins)
	Helper method to screen output the local bins.

Function Documentation

std::vector< std::size_t > Acts::Experimental::detail::binSequence	(	std::array< std::size_t, 2u >	minMaxBins,
		std::size_t	expand,
		std::size_t	nBins,
		Acts::detail::AxisBoundaryType	type
	)

Helper method to generate completely populated bin sequences that respect the boundary type of the axis.

Parameters

minMaxBins	estimated bin range (aka binning boundary box)
expand	the parameter to expand the view (extra window)
nBins	the maximum number of bins on this axis
type	the boundary type of the axis (for correct bin closure)

Note

for closed binning a span over half the bins flips direction

Returns

a vector of bins to be filled

Helper method to fill a range

Parameters

lmin	the minimum bin
lmax	the maximum bin

template<typename grid_type >

std::set<typename grid_type::index_t> Acts::Experimental::detail::localIndices	(	const grid_type &	grid,
		const std::vector< typename grid_type::point_t > &	queries,
		const std::vector< std::size_t > &	expansion = {}
	)

Helper method to fill local bins given a set of query points bin in between the extra points are filled, and a possible expansion of the bin window can be chosen.

Template Parameters

grid_type

the type of the grid that determines locall binning

Parameters

grid	the grid used for this
queries	the grid positions for the bin queries
expansion	are the additional (configured) number of bins to expand the view

Returns

a set of unique indices

These are the axis bounds type parameters - for correct bin sequences
