Detailed Description

Abstract interface for classes which compute the points of closest approach of 2 helices.
For a pair of states, the calculate methods have to be called before any of the other methods. This will do all calculations needed to get the result. It returns a status which says whether the calculation was successful. This should be checked before getting the result. If the status is false and the results querried, an exception will be thrown.

virtual GlobalPoint ClosestApproachOnHelices::crossingPoint ( ) const
pure virtual

Crossing point of the 2 helices, computed as an average of the points of closest approach. The average can be weighted or not, depending on the implementation.

Implemented in GCC11_FINAL< T, TOPO >, GCC11_FINAL< T, TOPO >, and TangentApproachInRPhi.

virtual float ClosestApproachOnHelices::distance ( ) const
pure virtual

Distance between the points of closest approach

Implemented in GCC11_FINAL< T, TOPO >, GCC11_FINAL< T, TOPO >, and TangentApproachInRPhi.

virtual std::pair<GlobalPoint, GlobalPoint> ClosestApproachOnHelices::points ( ) const
pure virtual

Points of closest approach on the 2 helices

Implemented in GCC11_FINAL< T, TOPO >, GCC11_FINAL< T, TOPO >, and TangentApproachInRPhi.
