class ConeBounds : public Acts::SurfaceBounds
- #include <Acts/Surfaces/ConeBounds.hpp>
Bounds for a conical surface, the opening angle is stored in \( \tan(\alpha) \) and always positively defined.
The cone can open to both sides, steered by \( z_min \) and \( z_max \).
Public Types

Values:
-
enumerator eAlpha
-
enumerator eMinZ
-
enumerator eMaxZ
-
enumerator eHalfPhiSector

-
ConeBounds(double alpha, bool symm, double halfphi = M_PI, double avphi = 0.) noexcept(false)
Constructor - open cone with alpha, by default a full cone but optionally can make a conical section.
- Parameters
alpha – is the opening angle of the cone
symm – is the boolean indicating if the cone is symmetric in +/- z
halfphi – is the half opening angle (default is pi)
avphi – is the phi value around which the bounds are opened (default=0)
-
ConeBounds(double alpha, double minz, double maxz, double halfphi = M_PI, double avphi = 0.) noexcept(false)
Constructor - open cone with alpha, minz and maxz, by default a full cone but can optionally make it a conical section.
- Parameters
alpha – is the opening angle of the cone
minz – cone expanding from minimal z
maxz – cone expanding to maximal z
halfphi – is the half opening angle (default is pi)
avphi – is the phi value around which the bounds are opened (default=0)
-
ConeBounds(const std::array<double, eSize> &values) noexcept(false)
Constructor - from parameters array.
- Parameters
values – The parameter array
-
~ConeBounds() override = default
-
inline double get(BoundValues bValue) const
Access to the bound values.
- Parameters
bValue – the class nested enum for the array access
-
virtual bool inside(const Vector2 &lposition, const BoundaryCheck &bcheck = true) const final
inside method for local position
- Parameters
lposition – is the local position to be checked
bcheck – is the boundary check directive
- Returns
is a boolean indicating if the position is inside
-
inline double r(double z) const
Return the radius at a specific z values.
- Parameters
z – is the z value for which r is requested
- Returns
is the r value associated with z
-
inline double tanAlpha() const
Return tangent of alpha (pre-computed)
-
virtual std::ostream &toStream(std::ostream &sl) const final
Output Method for std::ostream.
- Parameters
sl – is the ostrea into which the dump is done
- Returns
is the input obect
-
virtual BoundsType type() const final
Return the bounds type - for persistency optimization.
- Returns
is a BoundsType enum
-
inline virtual std::vector<double> values() const final
Return the bound values as dynamically sized vector.
- Returns
this returns a copy of the internal values
Private Functions
-
inline void checkConsistency() noexcept(false)¶
Check the input values for consistency, will throw a logic_exception if consistency is not given.
