Detailed Description

This is an accessor for cases where the material is filled in a global material vector that is accessed from the different material grids.

Member Typedef Documentation

grid_value_type

using Acts::GloballyIndexedMaterialAccessor::grid_value_type = std::size_t

Broadcast the grid_value_type.

Constructor & Destructor Documentation

GloballyIndexedMaterialAccessor()

Acts::GloballyIndexedMaterialAccessor::GloballyIndexedMaterialAccessor ( std::shared_ptr< std::vector< MaterialSlab > > gMaterial, bool shared = false )

explicit

Constructor with global material vector.

Parameters

gMaterial	Shared pointer to global material vector
shared	Whether material entries are shared across grid points

Member Function Documentation

scale()

template<typename grid_type>

void Acts::GloballyIndexedMaterialAccessor::scale	(	grid_type &	grid,
		double	scale )

Scale the material (by scaling the thickness).

Parameters

grid	the grid holding the indices into the global material vector
scale	the amount of the scaling

Note

this will scale only the bins touched by this grid, however, if there are shared bins, then it will throw an exception as the outcome is unpredictable.

slab()

template<typename grid_type>

const MaterialSlab & Acts::GloballyIndexedMaterialAccessor::slab	(	const grid_type &	grid,
		const typename grid_type::point_t &	point ) const

Direct const access to the material slap sorted in the grid.

Template Parameters

grid_type

the type of the grid, also defines the point type

Parameters

grid	the grid holding the indices into the global material vector
point	the lookup point (already casted from global, or filled from local)

Returns

the material slab from the grid bin associated to the lookup point

Member Data Documentation

globalMaterial

std::shared_ptr<std::vector<MaterialSlab> > Acts::GloballyIndexedMaterialAccessor::globalMaterial = nullptr

The internal storage of the material.

sharedEntries

bool Acts::GloballyIndexedMaterialAccessor::sharedEntries = false

Indicate if you have entries bins across different grids, e.g.

by running a compression/clustering algorithm.

It is the responsibility of the user to set this flag correctly.
