Class Acts::Experimental::DetectorVolumeBuilder

class DetectorVolumeBuilder : public Acts::Experimental::IDetectorComponentBuilder

A generic detector volume builder that uses an external builder for shape and portals and an internal structure builder for volume internals.

Note

Although this helper builds only a single volume, it is to the outside presented as a DetectorComponent with shell; like this it can be transparently be used for the downstream detector construction process.

Public Functions

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

Constructor with configuration arguments.

Parameters

  • cfg – is the configuration struct

  • logger – logging instance for screen output

virtual DetectorComponent construct(RootDetectorVolumes &roots, const GeometryContext &gctx) const final

Final implementation of a volume builder that is purely defined by an internal and external structure builder.

Parameters

  • roots – [in,out] the detector root volumes

  • gctx – The geometry context for this call

Returns

an outgoing detector component

struct Config

Nested configuration object.
