Role of Google Protocol Buffer in Kortex API

The Kortex API uses Google Protocol Buffer message objects1 to exchange data between client and server.

Google Protocol Buffer offers structured data objects with standard methods for each member field:

  • structured, nested objects
  • basic types and collections
  • getter/setter methods on basic types
  • iterators, dimension and appending methods on collections
  • many helpers (e.g. serialize/deserialize, I/O functions)

When using the Kortex API a developer will need to understand the Google Protocol Buffer feature set to maximize their efficiency.

Quick Start for C++ users

The following links provide some helpful guidance for C++ developer. You will find information about Kortex mechanism and some code examples.

Quick Start for Python users

To run the Python examples you will need to install the Python interpreter and the pip installation module.

Note that for C++ developers it could be useful to install the Python Kortex API to allow for quick tests and validations.

Here is some general information about the Python interpreter and the pip module manager.
