const xAOD::Vertex * getPrimaryVertex (const xAOD::VertexContainer *) const

Detailed Description

Creates a new ROI centred on an object deriving from xAOD::Jet adding a PV constraint.

Stores this new ROI in the output container, and links it to the Decision Object

The new EventView spawned by the parent EventViewCreatorAlgorithm of this tool will process in this new ROI.

In the majority of cases, this tool will be used to create the new ROI centred on the "feature" from the previous Step.
