Detailed Description

A helper class that fills surfaces into predefined grids.

assignToAll()

template<typename index_grid, typename indices>

void Acts::IndexGridFiller::assignToAll	(	index_grid &	iGrid,
		const indices &	idcs ) const

Helper method to fill a dedicated list of indices into the entire grid.

This is useful if e.g. certain objects are to be attempted in any case, regardless of their binning.

fill()

template<typename index_grid, typename indexed_objects, typename reference_generator>

void Acts::IndexGridFiller::fill	(	const GeometryContext &	gctx,
		index_grid &	iGrid,
		const indexed_objects &	iObjects,
		const reference_generator &	rGenerator,
		const typename index_grid::grid_type::value_type &	aToAll = {} ) const

This method takes a collection of objects and fills them into an index grid - it uses a reference generator for grid query points and then completes the bins in between.

It also allows for expanding the fill view.

Template Parameters

index_grid	the type of the index grid
indexed_objects	the type of the object container
reference_generator	the generator for reference points to be filled

Parameters

gctx	the geometry context of the operation
iGrid	[in,out] the index grid object to be filled
iObjects	the object container to be indexed
rGenerator	the reference point generator for position queries
aToAll	the indices that are assigned to all bins

Note

as this is a Detector module, the objects within the indexed_objects container are assumed to have pointer semantics

logger()

const Logger & Acts::IndexGridFiller::logger

(

)

const

Access to the logger.

Returns

a const reference to the logger

Member Data Documentation

binExpansion

std::vector<std::size_t> Acts::IndexGridFiller::binExpansion = {}

Bin expansion where needed - in integer bins.

oLogger

std::unique_ptr<const Logger> Acts::IndexGridFiller::oLogger

Initial value:

=
      getDefaultLogger("IndexGridFiller", Logging::INFO)

Screen output logger.

referenceExpansion

std::vector<double> Acts::IndexGridFiller::referenceExpansion = {}

Reference expansion - is applied before bin expansion.
