0006 /// Class derived from PixelTopology that serves as a proxy to the
0007 /// actual topology for a given PixelGeomDetType. In addition, the
0008 /// class holds a pointer to the surface deformation parameters.
0009 /// ProxyPixelTopology takes over ownership of the surface
0010 /// deformation parameters.
0011 ///
0012 /// All inherited virtual methods that take the predicted track
0013 /// state as a parameter are reimplemented in order to apply
0014 /// corrections due to the surface deformations.
0015 //
0016 /// The 'old' methods without the track predictions simply call
0017 /// the method of the actual topology.
