AUTOSAR SOME/IP Service Discovery Options: C++98/STL parsing library

FormatOptions are used to transport additional information to the entries. This includes forinstance the information how a service instance is reachable (IP-Address, TransportProtocol, Port Number).

This page hosts a formal specification of AUTOSAR SOME/IP Service Discovery Options using Kaitai Struct. This specification can be automatically translated into a variety of programming languages to get a parsing library.

Usage

Runtime library

All parsing code for C++98/STL generated by Kaitai Struct depends on the C++/STL runtime library. You have to install it before you can parse data.

For C++, the easiest way is to clone the runtime library sources and build them along with your project.

Code

Using Kaitai Struct in C++/STL usually consists of 3 steps.

  1. We need to create an STL input stream (std::istream). One can open local file for that, or use existing std::string or char* buffer.
    #include <fstream>
    
    std::ifstream is("path/to/local/file.some_ip_sd_options", std::ifstream::binary);
    
    #include <sstream>
    
    std::istringstream is(str);
    
    #include <sstream>
    
    const char buf[] = { ... };
    std::string str(buf, sizeof buf);
    std::istringstream is(str);
    
  2. We need to wrap our input stream into Kaitai stream:
    #include "kaitai/kaitaistream.h"
    
    kaitai::kstream ks(&is);
    
  3. And finally, we can invoke the parsing:
    some_ip_sd_options_t data(&ks);
    

After that, one can get various attributes from the structure by invoking getter methods like:

data.entries() // => get entries
