A quick hack to make a hex dumper for boost::arrays

boost_array_hex_dump.cpp

template<typename array_type, std::size_t array_size>
std::string hex_dump_array(const boost::array<array_type, array_size>& in_array)
{
    // 100 chars max stride. 2 chars per byte. 
    using namespace std;
    const uint32_t chunks_per_stride = 50 / (sizeof(array_type) + 1);
    uint32_t chunk_offset = 0;
    std::stringstream out_stream;
    std::string stride_txt;

    for(typename boost::array<array_type, array_size>::const_iterator i = in_array.begin();
        i != in_array.end();
        ++i, ++chunk_offset)
    {
        if(chunk_offset % chunks_per_stride == 0)
        {
            if(chunk_offset != 0)
            {
                out_stream << " " << stride_txt;
                stride_txt.clear();
                out_stream << "\n";
            }
            out_stream << "0x" << setw(4) << setfill('0') << hex << chunk_offset;
        }
        out_stream  << " " << setw(sizeof(array_type) * 2) << setfill('0') << hex << (uint64_t)*i;
        if(isgraph(*i)) // Not valid for all array_types!!
            stride_txt += string(1, *i);
        else
            stride_txt += "X";
    }

    out_stream << " " << stride_txt;
    out_stream << "\n";

    return out_stream.str();
}
