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.

Constructor & Destructor Documentation

RODFragment()

eformat::old::RODFragment::RODFragment	(	const uint32_t *	it,
		size_t	size_word )

To build a header given the containing buffer. I need to know where the header starts in order to do that.

Parameters

it	The position pointing the first word of this fragment
size_word	The size of this fragment, in words

Definition at line 22 of file RODFragment24.cxx.

    m_size(size_word)
{
  uint32_t m = marker();
  if (m != eformat::ROD) throw EFORMAT_WRONG_MARKER(m, eformat::ROD);
