class Acts::TrackingGeometryBuilder : public Acts::ITrackingGeometryBuilder

The Acts::TrackingGeometry Builder for volumes that wrap around another.

It retrieves an array of std::functions that build the TrackingGeometry sequentially in order, with the following options:

  • contained (e.g. a final insertion of a beam pipe of longer extend)

  • wrapped (e.g. an outer detector wrapping an inner one)

  • attached (e.g. a neighbor detector attaching to the previous one)

The returned volume of each step must be processable by the previous step

Public Functions

TrackingGeometryBuilder(const Config &cgbConfig, std::unique_ptr<const Logger> logger = getDefaultLogger("TrackingGeometryBuilder", Logging::INFO))

Constructor.

Parameters

  • [in] cgbConfig: is the configuration struct for this builder

  • [in] logger: logging instance

~TrackingGeometryBuilder() override = default

Destructor.

Config getConfiguration() const

Get configuration method.

Return

the current configuration

void setConfiguration(const Config &cgbConfig)

Set configuration method.

Parameters

  • cgbConfig: is the new configuration struct

void setLogger(std::unique_ptr<const Logger> newLogger)

set logging instance

Parameters

  • newLogger: the new logging instance

std::unique_ptr<const TrackingGeometry> trackingGeometry(const GeometryContext &gctx) const final

TrackingGeometry Interface method.

Return

a unique pointer to a TrackingGeometry

Parameters

  • gctx: geometry context of that building call

struct Config

Nested Configuration for the CylinderVolumeBuilder.
