Detailed Description

Actor class to assign volume identifiers to DetElements in a subdetector tree.

During the tree traversal the encoding information is also accumulated in a map indexed by the DetElement.

scanPhysicalVolume()

std::size_t DetElementVolumeIDs::scanPhysicalVolume ( DetElement &  parent, DetElement  e, PlacedVolume  pv, Encoding  parent_encoding, SensitiveDetector &  sd, PlacementPath &  chain  )

private

Scan a single physical volume and look for sensitive elements below.

Check if this particular volume is the placement of one of the children of this detector element. If the daughter placement is also a detector child, then we must reset the node chain.

For compounds the upper level sensitive detector does not exist, because there are multiple at lower layers
