Member Function Documentation

accumulate()

virtual void Acts::ISurfaceMaterialAccumulator::accumulate ( State & state, const GeometryContext & gctx, const std::vector< MaterialInteraction > & interactions, const std::vector< IAssignmentFinder::SurfaceAssignment > & surfacesWithoutAssignment ) const

pure virtual

Accumulate the material interaction on the surface.

Parameters

state	is the state of the accumulator
gctx	the geometry context
interactions	is the material interactions, with assigned surfaces
surfacesWithoutAssignment	are the surfaces without assignment

Note

this the track average over the binned material

Implemented in Acts::BinnedSurfaceMaterialAccumulator.

createState()

virtual std::unique_ptr< State > Acts::ISurfaceMaterialAccumulator::createState ( const GeometryContext & gctx ) const

pure virtual

Factory for creating the state.

Parameters

gctx	the geometry context

Returns

Unique pointer to a new state object for material accumulation

Implemented in Acts::BinnedSurfaceMaterialAccumulator.

finalizeMaterial()

virtual std::map< GeometryIdentifier, std::shared_ptr< const ISurfaceMaterial > > Acts::ISurfaceMaterialAccumulator::finalizeMaterial ( State & state, const GeometryContext & gctx ) const

pure virtual

Finalize the surface material maps.

Parameters

state	the state of the accumulator
gctx	the geometry context

Note

this does the run average over the (binned) material

Returns

Map of geometry IDs to finalized surface material objects

Implemented in Acts::BinnedSurfaceMaterialAccumulator.
