SingleBoundTrackParameters
: public Acts::SingleTrackParameters<ChargePolicy>¶ Charged and Neutrial Track Parameterisation classes bound to to a reference surface.
This is a single-component representation
Bound track parameters are delegating the transformation of local to global coordinate transformations to the reference surface Surface and thus need at contruction a Context object
- Note
This class holds shared ownership on the surface it is associated to.

Public Functions
Constructor of track parameters bound to a surface This is the constructor from global parameters, enabled only for charged representations.
The transformations declared in the coordinate_transformation yield the global parameters and momentum representation
- Parameters
[in] gctx
: is the Context object that is forwarded to the surface for local to global coordinate transformation[in] cov
: The covaraniance matrix (optional, can be nullptr) it is given in the measurement frame[in] parValues
: The parameter vector[in] surface
: The reference surface the parameters are bound to

- Parameters
[in] gctx
: is the Context object that is forwarded to the surface for local to global coordinate transformation[in] cov
: The covaraniance matrix (optional, can be nullptr) it is given in the curvilinear frame[in] position
: The global position of the track parameterisation[in] momentum
: The global momentum of the track parameterisation[in] dCharge
: The charge of the particle track parameterisation[in] dTime
: The time component of the parameters[in] surface
: The reference surface the parameters are bound to

SingleBoundTrackParameters
(const SingleBoundTrackParameters<ChargePolicy> ©)¶ copy constructor - charged/neutral
- Parameters
[in] copy
: The source parameters
-
SingleBoundTrackParameters
(SingleBoundTrackParameters<ChargePolicy> &&other)¶ move constructor - charged/neutral
- Parameters
[in] other
: The source parameters
-
~SingleBoundTrackParameters
() final = default¶ desctructor - charged/neutral checks if the surface is free and in such a case deletes it
-
SingleBoundTrackParameters<ChargePolicy> &
operator=
(const SingleBoundTrackParameters<ChargePolicy> &rhs)¶ copy assignment operator - charged/neutral
-
SingleBoundTrackParameters<ChargePolicy> &
operator=
(SingleBoundTrackParameters<ChargePolicy> &&rhs)¶ move assignment operator - charged/neutral checks if the surface is free and in such a case delete-clones it
-
RotationMatrix3D
referenceFrame
(const GeometryContext &gctx) const¶ access to the measurement frame, i.e.
the rotation matrix with respect to the global coordinate system, in which the local error is described.
For planar surface, this is identical to the rotation matrix of the surface frame, for measurements with respect to a line this has to be constructed by the point of clostest approach to the line, for cylindrical surfaces this is (by convention) the tangential plane.
- Parameters
[in] gctx
: is the Context object that is forwarded to the surface for local to global coordinate transformation
-
template<ParID_t
par

voidset
(const GeometryContext &gctx, ParValue_t newValue)¶ set method for parameter updates obviously only allowed on non-const objects
- Parameters
[in] gctx
: is the Context object that is forwarded to the surface for local to global coordinate transformation
