Struct Acts::Intersection

template<unsigned int DIM>
struct Acts::Intersection

Intersection struct used for position.

Public Types

enum Status

Nested Status enum.

Values:

enumerator missed
enumerator unreachable
enumerator reachable
enumerator onSurface

Public Functions

inline Intersection(const ActsVector<DIM> &sinter, double slength, Status sstatus)

Constructor with arguments.

Parameters

  • sinter – is the position of the intersection

  • slength – is the path length to the intersection

  • sstatus – is an enum indicating the status of the intersection

Intersection() = default

Default constructor.

inline explicit operator bool() const

Bool() operator for validity checking.

inline bool operator<(const Intersection<DIM> &si) const

Smaller operator for sorting,.

  • it respects the validity of the intersection

Parameters

si – is the intersection for testing

inline bool operator>(const Intersection<DIM> &si) const

Greater operator for sorting,.

  • it respects the validity of the intersection

Parameters

si – is the intersection for testing

Public Members

ActsVector<DIM>::Scalar pathLength{std::numeric_limits<double>::infinity()}

Signed path length to the intersection (if valid)

ActsVector<DIM> position = ActsVector<DIM>::Zero()

Position of the intersection.

Status status = {Status::unreachable}

The Status of the intersection.
