# Custom structured data format definitions
|
||
|
|
|
||
|
|
Files in this folder describe structured data formats that are generated by
|
||
|
|
GNSS-SDR. They use [Protocol Buffers](https://developers.google.com/protocol-buffers/)'
|
||
|
|
[proto3](https://developers.google.com/protocol-buffers/docs/proto3) syntax.
|
||
|
|
|
||
|
|
From those files, the protocol buffer compiler creates classes that implement
|
||
|
|
automatic encoding and parsing of the protocol buffer data with an efficient
|
||
|
|
binary format. The generated classes provide getters and setters for the fields
|
||
|
|
that make up a protocol buffer and take care of the details of reading and
|
||
|
|
writing it as a unit. Importantly, the protocol buffer format supports the idea
|
||
|
|
of extending the format over time in such a way that the code can still read
|
||
|
|
data encoded with the old format.
|
||
|
|
|
||
|
|
Just grab these files if you are developing a client application for GNSS-SDR.
|
||
|
|
You are free to use C++, Java, Python, C#, Dart, Go or Ruby, among other
|
||
|
|
languages. A tutorial to create a simple application using Protocol Buffers and
|
||
|
|
a `.proto` file in C++ is available at
