Protocol buffers are theįlexible, efficient, automated solution to solve exactly this problem. Instead of these options, you can use protocol buffers. 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.

Wired for that format are spread around, it’s very hard to extend the Also, asįiles accumulate data in the raw format and copies of software that are Time, this is a fragile approach, as the receiving/reading code must beĬompiled with exactly the same memory layout, endianness, etc.

The raw in-memory data structures can be sent/saved in binary form.

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 C++.

Use the C++ protocol buffer API to write and read messages.
