Update the GenParticleSimWhiteList tool to work with ShadowEvents
Builds upon !63457 (merged).
This MR updates the GenParticleSimWhiteList
IGenParticleFilter
tool to deal with the case that the GenParticle
and GenVertex
objects associated with decays of quasi-stable particles predefined by the generator may not be present in the output GenEvent
. This is ability is switched off by default, so no change in output is expected.
Part of the changes from !63059 (merged).
