Member Function Documentation

Propagator* trkf::PropAny::clone ( ) const

inlineoverridevirtual

Clone method.

Implements trkf::Propagator.

Definition at line 31 of file PropAny.h.

std::optional< double > trkf::PropAny::origin_vec_prop	(	KTrack &	trk,

	)		const

overridevirtual

Propagate without error to surface whose origin parameters coincide with track position.

Propagate without error to dynamically generated origin surface. Optionally return propagation matrix.

Arguments:

trk - Track to propagate. porient - Orientation surface. prop_matrix - Pointer to optional propagation matrix.

Returned value: propagation distance + success flag.

Propagation distance is always zero after successful propagation.

Implements trkf::Propagator.

overridevirtual

Propagate without error.

Propagate without error. Optionally return propagation matrix and noise matrix. This method tests the type of the destination surface, and calls the corresponding typed propagator.

Arguments:

trk - Track to propagate. psurf - Destination surface. dir - Propagation direction (FORWARD, BACKWARD, or UNKNOWN). doDedx - dE/dx enable/disable flag. prop_matrix - Pointer to optional propagation matrix. noise_matrix - Pointer to optional noise matrix.

Returned value: propagation distance + success flag.

Implements trkf::Propagator.
