0004 /// ProxyStripTopology
0005 ///
0006 /// Class derived from StripTopology that serves as a proxy to the
0007 /// actual topology for a given StripGeomDetType. In addition, the
0008 /// class holds a pointer to the surface deformation parameters.
0009 /// ProxyStripTopology takes over ownership of the surface
0010 /// deformation parameters.
0011 ///
0012 /// All inherited virtual methods that take the
0013 /// predicted track state as a parameter are reimplemented in order
0014 /// to apply corrections due to the surface deformations.
0015 //
0016 /// The 'old' methods without the track predictions simply call
0017 /// the method of the actual StripTopology.
0018 /// While one could easily deduce corrections from the given
0019 /// LocalPosition (and track angles 0) when converting from local frame
0020 /// to measurement frame, this is not done to be consistent with the
0021 /// methods converting the other way round where the essential y-coordinate
0022 /// is basically missing (it is a 1D strip detector...)
