int* decode(int *)

with the "what" parameter you can decide which aspect of the data is made available. This class is one of those which have several different "kinds" of data; we use this to bring up the misc. items in the FEM headers and trailers.

There are a few standard ones listed below. The one special for this packet is the iValue(i, "CHECKCTR") call, which gives you the check counter (someone can give me a better word) for row i.

A new "MISMATCH" query was introduced. iValue(0, "MISMATCH") returns 0 (false) when all the check values match. If not, you will get the number of the row where the first deviating check wird appears, which is true (you have to look with "CHECKCTR" if there are more).

So you can just do if (p->iValue(0, "MISMATCH") ) do_something();

The standard "what" parameters for an FEM packet are

 packet->iValue(0,"EVTNR")  The FEM event number
 packet->iValue(0,"MODULE")   The Module ID
 packet->iValue(0,"BCLK")     Beam clock value from FEM
 packet->iValue(i,"PARITY")   The longitudinal parity
