Language bindings generated from the GTFS-realtime protocol buffer spec for popular languages.
GTFS-realtime is a data format for communicating real-time information about public transit systems. GTFS-realtime data is encoded and decoded using Protocol Buffers, a compact binary representation designed for fast and efficient processing. The data schema itself is defined in gtfs-realtime.proto.
To work with GTFS-realtime data, a developer would typically use the
gtfs-realtime.proto schema to generate classes in the programming language of
their choice. These classes can then be used for constructing GTFS-realtime
data model objects and serializing them as binary data or, in the reverse
direction, parsing binary data into data model objects.
Because generating GTFS-realtime data model classes from the
gtfs-realtime.proto schema is such a common task, but also one that sometimes
causes confusion for first-time developers, this project aims to provide
pre-generated GTFS-realtime language bindings for a number of the most popular
programming languages. Where possible, these language bindings will be
published as packages to facilitate their use in other projects.
We don't provide generated code for C++, use the official protoc compiler for that (from here or here)
