Protocol buffers are the flexible, efficient, automated solution to solveĮxactly this problem. Navigating simple fields in a class normally would be. However, XML is notoriously space intensive, andĮncoding/decoding it can impose a huge performance penalty on applications.Īlso, navigating an XML DOM tree is considerably more complicated than This can be a good choice if you want to share data with otherĪpplications/projects. (sort of) human readable and there are binding libraries for lots of This approach can be very attractive since XML is Parsing code, and the parsing imposes a small run-time cost. This is a simple andįlexible approach, although it does require writing one-off encoding and String – such as encoding 4 ints as “12:3:-23:67”. You can invent an ad-hoc way to encode the data items into a single.rialization has aīut this does not offer the full features of protocol buffers. This does not work very well if you need to shareĭata with applications written in C++ or Python. How do you serialize and retrieve structured data like this? There are a few

The address book has a name, an ID, an email address, and a contact phone

The example we’re going to use is a very simple “address book” application thatĬan read and write people’s contact details to and from a file. This isn’t a comprehensive guide to using protocol buffers in Kotlin.

Use the Kotlin protocol buffer API to write and read messages.
