class AliHLTTPCClusterFinder;
class AliHLTTPCDigitReader;
* Implementation of the cluster finder component.
* The component implements the interface methods of the @ref AliHLTProcessor.
* The actual cluster finding algorithm is implemented in @ref AliHLTTPCClusterFinder.
- * The component can handle unpacked and packed data of different formats via the
- * AliHLTTPCDigitReader implementations. Two components are registered, the
- * TPCClusterFinderUnpacked and the TPCClusterFinderPacked. The latter one can
- * instantiate different digit readers depending on the arguments.
+ * Two components are registered, TPCClusterFinderPacked and TPCClusterFinderDecoder.
+ * TPCClusterFinderDecoder use the AliTPCRawStream class for decoding of the data, while TPCClusterFinderDecoder
+ * use the AliAltroDecoder for decoding the data.
+ *
+ * TPCClusterFinderDecoder is the fastest of the two, this is due to that the AliAltroDecoder
+ * returns data in a bunch format. A bunch consist of consecutive signals.
+ * TPCClusterFinderPacked first have to read the data one by one, which means that row, pad and
+ * time signals have to be compared between each new digit, which leads to a slower alorithm.
*
- * The component has the following component arguments:
- * - adc-threshold ADC count threshold for zero suppression, if <0 the base line
- * calculation and subtraction is switched off
- * - pp-run set parameters specific to a pp run; currently this switches
- * cluster deconvolution off for pp runs (not true for unsorted reading)
- * - unsorted if 1 the data will be read unsorted in to a PadArray object. This should
- * only be done on patch level since it use a lot of memory
- * - patch specify on which patch to resd the data unsorted
*
+ * The clusterfinder is now using the AliTPCTransform instead of the AliHLTTPCTransform for
+ * transformations from row, pad time -> x,y,z.
+ *
