Detailed Description

template<typename grid_t, typename extractor_type, typename filler_type>
class Acts::Experimental::IndexedUpdatorImpl< grid_t, extractor_type, filler_type >

This is an index grid based navigation state updator, it uses an extractor type and a filler type to handle the navigation state.

Note

a transform is applied p3l = transform * p3 in order to allow shifted, transformed grids

It can be used for volumes, surfaces at convenience

Template Parameters

grid_t	is the type of the grid
extractor_type	is the helper to extract the object
filler_type	is the helper to fill the object into the nState

void Acts::Experimental::IndexedUpdatorImpl< grid_t, extractor_type, filler_type >::update ( const GeometryContext &  gctx, NavigationState &  nState  ) const

inline

updates the navigation state with objects from the grid according to the filling type AFTER applying p3loc = transform * p3

Parameters

gctx	is the Geometry context of this call
nState	the navigation state to which the surfaces are attached

Note

this is attaching objects without intersecting nor checking
