Detailed Description

Registry-facing handle on the ACTS tracking geometry.

This is a thin shim over TrackingGeometryManager: both access paths hand out the very same geometry object, so a workflow can mix them freely. What the service adds is DPL-owned lifetime (the geometry is released on device exit rather than at static destruction) and retrieval through the registry:

auto& actsGeo = pc.services().get<o2::acts::ActsGeometryService>();
const auto& tg = actsGeo.getGeometry();
o2::acts::ActsGeometryService::getGeometry
const Acts::TrackingGeometry & getGeometry() const
Definition ActsGeometryService.cxx:30

Registered with ServiceKind::DeviceGlobal: one instance per device process, shared by every data processor in it, and safe to read from several threads once built.

Member Function Documentation

◆ getGeometry()

const Acts::TrackingGeometry & o2::acts::ActsGeometryService::getGeometry ( ) const

Builds on first use. Requires gGeoManager to be live and a builder to have been installed on TrackingGeometryManager.
