Detailed Description

Author: M. De Mattia (demattia@pd.infn.it) 25/10/2010:

Dependent record used to combine the SiStripBaseDelays and provide the reconstruction with a single delay value.
When the object is built the list of values is stored in boost::unordered_map which, for the number of modules in the Tracker (~15000) resulted much faster (more than a factor 2) than a std::map or a lower_bound search in a sorted vector.
The base delays must be filled in together with the sign they will get in the summation: baseDelay1*sign1 + baseDelay2*sign2 + ...
Pointers to the baseDelays are stored and after the fill is complete the method "makeDelay" must be called to build the internal map.
This additional step is required such that we don't build the map anytime a new baseDelay is inserted and we don't make checks anytime the getDelay method is called.
NOTE: Even if the code does not rely on the presence of the same detIds in all the baseDelays, this condition should be fullfilled for consistency. The code checks only that the number of detIds is the same in all baseDelays.

const SiStripBaseDelay* SiStripDelay::getBaseDelay ( const uint32_t index ) const [inline]

The second parameter allows to specify which delay to retrieve, considering that they are in input order. NOTE that no protection is inside the method (because we want to keep it very light) therefore it is the caller duty to check that the index is in the correct range.
