Detailed Description

Base Class for a Detector Layer in the Tracking realm. An actual implemented Detector Layer inheriting from this base class has to inherit from a specific type of Surface as well. In addition, a Layer can carry:

a SurfaceArray of Surfaces holding the actual detector elements or subSurfaces.
LayerMaterialProperties for Surface-based materialUpdates
an OverlapDescriptor (mainly used for blind extrapolation)
a pointer to the TrackingVolume (can only be set by such)
an active/passive code : 0 - activ 1 - passive [....] - other

◆ subSurfaceReference()

const Trk::Surface * Trk::Layer::subSurfaceReference ( unsigned int idx = 0 ) const

Return a reference sub surface of the layer, usually the first one in the array.

if an index is given (and the index is in range), this surface is returned
