20 * @class AliHLTTPCCASliceOutput
22 * AliHLTTPCCASliceOutput class is used to store the output of AliHLTTPCCATracker{Component}
23 * and transport the output to AliHLTTPCCAGBMerger{Component}
25 * The class contains all the necessary information about TPC tracks, reconstructed in one slice.
26 * This includes the reconstructed track parameters and some compressed information
27 * about the assigned clusters: clusterId, position and amplitude.
