eProsima Fast DDS-Gen is a Java application that generates
eProsima Fast DDS C++ or Python source code using the data types
defined in an IDL (Interface Definition Language) file. This
generated source code can be used in any Fast DDS application in
order to define the data type of a topic, which will later be
used to publish or subscribe.
