Detailed Description

Abstract component defining the conversion between the local frame of a detector and the frame defined by the readout channels , the so called measurement frame. For example, in a strip detector the strips define a coordinate frame (from 0 to Nstrips in one direction and from 0 to 1 in the other), and each local point can be mapped to a point in this frame. The mapping may be non-linear (for example for trapezoidal strips).

The topology should be the ONLY place where this mapping is defined. The Digitizer uses the Topology to transform energy deposits in the local frame into signals on the readout channels, and the clusterizer (or the RecHit) uses the Topology for the inverse transformation, from channel numbers to local coordinates.

If the surface of a Topology deviates from its perfect shape, e.g. a bowed instead of a flat surface (bowed silicon sensors) or if built from two surfaces that might be misaligned with respect to each other (double sensor silicon modules), conversion might depend on a track prediction. Conversions from local to measurement frame therefore need the 'LocalTrackAngles', conversions the other way round need also track position predictions, bound together with the angles to a 'LocalTrackPred'. Default implementation of methods requiring more arguments is to call the simple method, ignoring the track state. Concrete implementations should overwrite this where appropiate.
