Detailed Description

Monte Carlo truth information used for tracking validation.

Object with references to the original SimTrack and parent and daughter TrackingVertices. Simulation with high (~100) pileup was taking too much memory so the class was slimmed down and copies of the SimHits were removed.

Constructor & Destructor Documentation

TrackingParticle() [1/2]

TrackingParticle::TrackingParticle

(

)

Default constructor. Note that the object will be useless until it is provided with a SimTrack and parent TrackingVertex.

Most of the methods assume there is a SimTrack and parent TrackingVertex set, so will either crash or give undefined results if this isn't true. This constructor should only be used to create a placeholder until setParentVertex() and addG4Track() can be called.

                                   {
  // No operation
