Introduction

This package contains the AthAlgTools that retrieve tracking data (tracks, track segments and vertices) from StoreGate and forward them to the formatting tool. Each tool implements the IDataRetriever interface, through which it is called from the AlgoJiveXML.

Retrievers

• JiveXML::SegmentRetriever - Properties
  • none

Retrieved Data
