Detailed Description

template<typename ChargePolicy>
class Acts::SingleCurvilinearTrackParameters< ChargePolicy >

Charged and Neutrial Curvilinear Track representation This is a single-component representation.

Note: the curvilinear representation is bound to the curvilinear planar surface represenation. I.e. the local parameters are by construction (0,0), the curvilinear surface is characterised by being perpendicular to the track direction. It's internal frame is constructed with the help of the global z axis.

Parameters

gctx	The current geometry context object, e.g. alignment It is ignored for Curvilinear parameters

update of the track parameterisation only possible on non-const objects, enable for local parameters

Template Parameters

ParID_t The parameter type

Parameters

gctx	The current geometry context object, e.g. alignment
newValue	The new updaed value

For curvilinear parameters the local parameters are forced to be (0,0), hence an update is an effective shift of the reference
