public class DecoderWriter extends HipoToHipoWriter
Combined with DecoderReader, a port of the standard "decoder" to CLARA. 1. Converts EVIO to HIPO, translation tables, pulse extraction 2. Copies special banks on-the-fly to new tag-1 events 3. Caches helicity states and scaler readouts, for later use in post-processing. 4. Upon close, writes the helicity sequence to HEL::flip banks in new tag-1 events.
