Member Data Documentation

m_arrayOfWriteHandleKeys

SG::WriteHandleKeyArray<xAOD::AFPToFTrackContainer> AFP_TDLocRecoTool::m_arrayOfWriteHandleKeys {this, "AFPToFTrackContainerList", {"AFPToFTrackContainer"}, "List of output containers"}

private

Array of unique write handle keys for track output containers.

Each write handle key has to be unique and in sync with m_recoToolsList. It's possible for several track reco algorithms contributing to the common container. Ideally, one should setup track reco containers (in AFP_LocReco/AFP_LocReco.py) and let the python script pick unique names.

Definition at line 53 of file AFP_TDLocRecoTool.h.

m_recoToolsList

ToolHandleArray<IAFPTDLocRecoTrackAlgTool> AFP_TDLocRecoTool::m_recoToolsList {this,"RecoToolsList",{},"List of AFP ToF track reconstruction tools"}

private

Vector of tool handles to be used for tracks reconstruction.

Each station has its own track reco algorithm. This array contains all of them
