Detailed Description

template<size_t MAX_SIZE = 8192, bool BOUNDS_CHECKS = true>
class o2::framework::RawParser< MAX_SIZE, BOUNDS_CHECKS >

the O2 raw data O2 raw data is organized in pages of a fixed size, each page starts with the RAWDataHeader The page size may actually be smaller than the maximum size, depending on the header fields.

The parser class works on a contiguous sequence of raw pages in a raw buffer. Multiple versions of RAWDataHeader are supported transparently and selected depending on the version field of the header.

Usage:

// option 1: parse method
RawParser parser(buffer, size);
auto processor = [&count](auto data, size_t size) {
  std::cout << "Processing block of size " << size << std::endl;
};
parser.parse(processor);

// option 2: iterator
RawParser parser(buffer, size);
for (auto it = parser.begin(), end = parser.end(); it != end; ++it, ++count) {
  std::cout << "Iterating block of size " << it.size() << std::endl;
  auto dataptr = it.data();
}

TODO:

• iterators are not independent at the moment and this can cause conflicts, this must be improved
