Constructor & Destructor Documentation

FRDEventMsgView::FRDEventMsgView

(

void *

buf

)

This class is used to view the contents of "FED Raw Data" (FRD) events. Initially, the only time that such events are created is when an error occurs in the HLT. So, in the beginning, "error event" == "FRD event". However, if new ways of creating events of this type are added to the HLT, hopefully this class can be used or upgraded to handle those events as well.

08-Aug-2008 - KAB - Initial Implementation 06-Oct-2008 - KAB - Added lumi block number

Format: uint32 - run number uint32 - lumi number uint32 - event number 1024 * uint32 - size values for all 1024 FED buffers variable size - FED data Constructor for the FRD event message viewer.
