Detailed Description

Implements the access methods and checking for the ROD header object, present in the event format stream. Manipulating ROD's is a bit different than the other fragments, as one can't know its ending position. There are two ways to solve that: the first being to give a pointer and a size, but the second, a bit more elegant, to indicate the end of the ROD instead of its begin.

◆ RODFragment()

eformat::old::RODFragment::RODFragment ( const uint32_t *  it,

Parameters
itThe position pointing the first word of this fragment
size_wordThe size of this fragment, in words
