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.
All parsing code for Java generated by Kaitai Struct depends on the Java runtime library. You have to install it before you can parse data.
The Java runtime library is published in the Maven Central Repository. Refer to the artifact page for instructions how to add it into your project with the build tool that you use.
Parse a local file and get structure in memory:
SomeIpSdOptions data = SomeIpSdOptions.fromFile("path/to/local/file.bin");
Or parse structure from a byte array:
byte[] someArray = new byte[] { ... };
SomeIpSdOptions data = new SomeIpSdOptions(new ByteBufferKaitaiStream(someArray));
After that, one can get various attributes from the structure by invoking getter methods like:
data.entries() // => get entries
// This is a generated file! Please edit source .ksy file and use kaitai-struct-compiler to rebuild
