Struct ProtoLayer

Struct Documentation

struct Acts::ProtoLayer

Encapsulates min/max boundaries that will be turned into a layer.

The struct allows this information to be obtained in a consistent way, or be caller provided.

Public Types

using Range = std::pair<double, double>

The envelope parameters.

Public Functions

ProtoLayer(const GeometryContext &gctx, const std::vector<const Surface*> &surfaces)

Constructor.

Loops over a provided vector of surface and calculates the various min/max values in one go. Also takes into account the thickness of an associated DetectorElement, if it exists.

Parameters

  • gctx: The current geometry context object, e.g. alignment

  • surfaces: The vector of surfaces to consider

ProtoLayer(const GeometryContext &gctx, const std::vector<std::shared_ptr<const Surface>> &surfaces)

Constructor.

Loops over a provided vector of surface and calculates the various min/max values in one go. Also takes into account the thickness of an associated DetectorElement, if it exists.

Parameters

  • gctx: The current geometry context object, e.g. alignment

  • surfaces: The vector of surfaces to consider

ProtoLayer() = default
void add(const GeometryContext &gctx, const Surface &surface)

Add a surface, this will also increase the extent.

Parameters

  • gctx: The current geometry context object, e.g. alignment

  • surface: The surface which is added to the ProtoLayer

double max(BinningValue bval, bool addenv = true) const

Parameters

  • bval: The accessed binning value

  • addenv: The steering if enevlope is added or not

double medium(BinningValue bval, bool addenv = true) const

Parameters

  • bval: The accessed binning value

  • addenv: The steering if enevlope is added or not

double min(BinningValue bval, bool addenv = true) const

Get the parameters : min.

Parameters

  • bval: The accessed binning value

  • addenv: The steering if enevlope is added or not

double range(BinningValue bval, bool addenv = true) const

Parameters

  • bval: The accessed binning value

  • addenv: The steering if enevlope is added or not

const std::vector<const Surface*> &surfaces() const

Give access to the surfaces used/assigned to the ProtoLayer.

std::ostream &toStream(std::ostream &sl) const

Output to ostream.

Parameters

  • sl: the input ostream
