20// Buffer to read RAW ALTRO FMD format from a AliRawReader
21//
7684b53c 22// This class derives from AliAltroBuffer, but overloads the memer
23// function Next to do some extra processing. In particular, it tries
24// to autodetect the sample rate. If zero-suppression was used when
25// writing the raw data, then the automatic discovery will not work,
26// and the sample rate should be set explicitly.
