Detailed Description

Base class for track candidates generation using space points information.

In AthenaMT, event dependent cache inside ISiSpacePointsSeedMaker is not preferred. SiSpacePointsSeedMakerEventData class holds event dependent data for ISiSpacePointsSeedMaker and its object is instantiated in SiSPSeededTrackFinder::execute.

Example implementation

SiSpacePointsSeedMakerEventData seedEventData;
seedsmaker->newEvent(seedEventData, -1);
 
std::list<Trk::Vertex> vertices;
seedsmaker->find2Sp(seedEventData, vertices);
 
const InDet::SiSpacePointsSeed* seed = nullptr;
while ((seed=seedsmaker->next(seedEventData))) {
    do some method with two space points seed;
}
 
seedsmaker->find3Sp();
while ((seed=seedsmaker->next(seedEventData))) {
    do some method with three space points seed;
}
 
seedsmaker->findVSp();
while ((seed=seedsmaker->next(seedEventData))) {
    do some method with variable number space points seed;
}
