fastddsgen - IDL source code generator


fastddsgen [options] FILE.idl [FILE.idl ...]


fastddsgen is a command line tool that generates eProsima Fast DDS 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.

To declare the structured data, the IDL format must be used. IDL is a specification language, made by OMG (Object Management Group), which describes an interface in a language independent manner, allowing communication between software components that do not share the same language. The eProsima Fast DDS-Gen tool reads the IDL files and parses a subset of the OMG IDL specification to generate source code for data serialization. This subset includes the data type descriptions included in Defining a data type via IDL. The rest of the file content is ignored.
