◆ sysInitialize()

virtual StatusCode AthCommonDataStore< AthCommonMsg< AlgTool > >::sysInitialize ( )

overridevirtualinherited

Perform system initialization for an algorithm.

We override this to declare all the elements of handle key arrays at the end of initialization. See comments on updateVHKA.

Reimplemented in asg::AsgMetadataTool, AthCheckedComponent< AthAlgTool >, AthCheckedComponent<::AthAlgTool >, and DerivationFramework::CfAthAlgTool.

◆ sysStart()

virtual StatusCode AthCommonDataStore< AthCommonMsg< AlgTool > >::sysStart ( )

overridevirtualinherited

Handle START transition.

We override this in order to make sure that conditions handle keys can cache a pointer to the conditions container.

◆ updateTrackNumbering()

void Trk::JetFitterInitializationHelper::updateTrackNumbering ( VxJetCandidate * myJetCandidate )

static

Does the update of the ordering of the vertices along the jetaxis.

This is needed after you make a change to the number of clusters (initially single tracks) of the VxJetCandidate, because you need to have for each VxVertexOnJetAxis a number stored which tells you where the corresponding position along the jet axis is stored in the RecVertexPositions (position + covariance matrix), which is then used to read/store the fit result.

The method initializeJetClusters already calls this update during its initialization of the VxJetCandidate.
