Detailed Description

Class representing the HLT extra payload stored in HLT::HLTResult::getExtras()

The members storing the data are public. New members should be added whenever additional storage is needed. The reserved anonymous member should only be used as a last resort.

If all members of this class are set to their default values (see empty()) a call to serialize() will do nothing. A deserialization from empty storage will result in a default constructed object.

Whenever you modify this class run 'make check'.
