Member Data Documentation

theMonoBounds

const Bounds* AlignableSiStripDet::theMonoBounds

private

The following four members are needed to recalculate the surface in consistifyAlignments, to get rid of a GluedDet* which is disregarded since it could become an invalid pointer in the next event (theoretically...). But this solution is not better, the references for the types would become invalid together with the GeomDets they are taken from. StripGeomDetType has neither clone() and nor a decent copy constructor, so I cannot go the the same way as for the bounds. Sigh!
