Detailed Description

This is an accessor for cases where the material is directly stored in the grid, it simply forwards the grid entry in const and non-const way.

Member Function Documentation

scale()

template<typename grid_type>

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

Scale the material (by scaling the thickness).

Parameters

grid	the grid (ignored)
scale	the amount of the scaling

Note

this is not particularly fast

slab()

template<typename grid_type>

const MaterialSlab & Acts::GridMaterialAccessor::slab	(	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
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
