Class Acts::LineBounds

class LineBounds : public Acts::SurfaceBounds

Bounds for a LineSurface.

Public Types

enum BoundValues


enumerator eR
enumerator eHalfLengthZ
enumerator eSize

Public Functions

LineBounds() = delete
inline LineBounds(double r, double halfZ) noexcept(false)


  • r – is the radius of the cylinder, default = 0.

  • halfZ – is the half length in z, defualt = 0.

inline LineBounds(const std::array<double, eSize> &values) noexcept(false)

Constructor - from fixed size array.


values – The parameter values

~LineBounds() override = default
inline double get(BoundValues bValue) const

Access to the bound values.


bValue – the class nested enum for the array access

virtual bool inside(const Vector2 &lposition, const BoundaryCheck &bcheck) const final

Inside check for the bounds object driven by the boundary check directive Each Bounds has a method inside, which checks if a LocalPosition is inside the bounds Inside can be called without/with tolerances.

  • lposition – Local position (assumed to be in right surface frame)

  • bcheck – boundary check directive


boolean indicator for the success of this operation

virtual std::ostream &toStream(std::ostream &sl) const final

Output Method for std::ostream.


sl – is the ostream to be dumped into

virtual BoundsType type() const final

Return the bounds type - for persistency optimization.


is a BoundsType enum

inline virtual std::vector<double> values() const final

Return the bound values as dynamically sized vector.


this returns a copy of the internal values
