Detailed Description

template<typename T>
class o2::itsmft::ClustersPerLayer< T >

< Container of the ITS/MFT clusters supplied either as a single (monolithic) array or per layer (staggered readout). The clusters of all layers are kept in a single vector, layer by layer, with the per-layer starting offsets recorded, so that a cluster referred to by the composed ID (layer << ClusLayerShift) + index_in_layer can be looked up directly. With the monolithic input only the layer slot 0 is filled and the composed ID coincides with the flat cluster index, hence the same lookup works for both cases.

The conversion of the compact clusters to the stored objects is detector specific (and needs the geometry), so it is left to the caller: the container only records where each layer starts. Expected usage (nLr == 1 for the monolithic input): cont.init(nLr); for (int lr = 0; lr < nLr; lr++) { cont.beginLayer(lr); auto pattIt = recoData.getITSClustersPatterns(lr).begin(); o2::its::ioutils::convertCompactClusters(recoData.getITSClusters(lr), pattIt, cont.getClusters(), dict); } cont.finalize(); after which cont[composedID] gives the cluster referred to by a track cluster reference.
