Detailed Description

Pseudo-track object for TotallyCheatTracks example.

This class represents a reconstructed track via a trajectory in phase space (position plus momentum), sampled in many points, and in addition a particle identification code representing the type of the original particle.

It is expected to be unrealistically precise for a reconstructed object, by being constructed from simulated "truth" information.

This track object does not implement the standard interface of a LArSoft track (recob::Track). It can present a standard LArSoft recob::Trajectory though.

Member Typedef Documentation

using lar::example::CheatTrack::PDGID_t = int

Type of the particle ID.

Definition at line 53 of file CheatTrack.h.

Constructor & Destructor Documentation

lar::example::CheatTrack::CheatTrack ( )

default

Default constructor, only for ROOT I/O (do not use it!).

lar::example::CheatTrack::CheatTrack ( recob::Trajectory &&  traj, PDGID_t  pid  )

inline

Constructor from trajectory (stolen) and particle ID.

Parameters

traj	the reconstructed trajectory of the track
pid	particle ID, in PDG standard

The trajectory in traj is moved into this object, and it will not be valid in the caller scope any more.

Definition at line 69 of file CheatTrack.h.

: fTraj(std::move(traj)), fPDGID(pid) {}

Member Function Documentation

template<typename Stream >

void lar::example::CheatTrack::dump	(	Stream &&	out,
		unsigned int	verbosity,
		std::string	indent,
		std::string	firstIndent
	)		const

Prints the content of this object into an output stream.

Template Parameters

Stream

type of the output text stream

Parameters

out	the output text stream
verbosity	the amount of information printed (default: DefaultDumpVerbosity)
indent	indentation string for all output except the first line (default: none)
firstIndent	indentation string for the first line (default: as indent)

Verbosity level is the same as the one of recob::Trajectory::Dump(). In addition, the momentum and particle ID are always printed.
