Detailed Description

Predicate class to check for the containment of segments in a phi0 curv hough space part.

Unlike hits segments occupy only a point in the hough space.

Member Function Documentation

operator()() [1/3]

Weight operator() ( const CDCFacet *  facet, const Phi0CurvBox *  phi0CurvBox  )

inlineprivate

Checks if the given hit triplet is considered part of the hough box in phi0, curvature space.

Returns a finit weight if it is contained, NAN if not contained.

                      : NAN;
        // All facets are currently worth the same weight
        // Facets contain three hits but in general contribute only one
        // additional hit due to overlaps with neighboring facets.
        // Hence we stick with 1 as weight here.
      }

        const Vector2D& lowerPhi0Vec = phi0CurvBox->getLowerPhi0Vec();

operator()() [2/3]

Weight operator() ( const CDCSegment2D *  segment, const Phi0CurvBox *  phi0CurvBox  )

inlineprivate

Checks if the segment is contained in a phi0 curv hough space.

Returns the size of the segment if it is contained, returns NAN if it is not contained. The method simply assumes that the segment has been fitted with origin constraint and simply uses the values from the contained trajectory The calling code has to ensure this situation

operator()() [3/3]

Weight operator() ( const CDCTrajectory2D *  trajectory2D, const Phi0CurvBox *  phi0CurvBox  )

inlineprivate

Checks if the given trajectory is considered part of the hough box in phi0, curvature space.

Returns a finit weight if it is contained, NAN if not contained.
