Detailed Description

DHC frame wrapper class.

Contains functions common for all type of frames (CRC etc) Provides a union pointer to the different struct types See Data format definitions [BELLE2-NOTE-TE-2016-009] on https://docs.belle2.org/

Member Function Documentation

check_padding()

void check_padding

(

PXDErrorFlags &

errormask

)

check padding and return it

TODO many false positives, we should remove that check after we KNOW that it has been fixed in DHH Firmware

Definition at line 223 of file PXDRawDataStructs.cc.
