We have decided to change this Example to a new BasicConfigurationExample instead of overwrite the current HelloWorldExample.

[jparisu]

Extra configurations by arguments could be added in the future (maybe future PRs) :

• allow more than publisher|subscriber as input (i.e. p|pub|writer|talker etc.)
• change type name (useful for ROS2)
• ROS2 mangling
• allow partitions
• create multiple publishers and/or subscribers in the same process (useful to check Intraprocess)
• Add TCP to available transports
• Active statistics

[jparisu]

In general

• Please, change the name of the files so they fit with the name of the directory and the example (there are already too much HelloWorldPublisher.cpp files in the repository)
• Add comments to each class and method in the header files so the example is easy to read and reproduce

I'd like this example to support data-sharing. You'd need to update the type and re-generate the type support. I'd also add a flag to disable it

[EduPonz]

As discussed off-line, setting a transport should disable data-sharing, else, it should use whatever Fast DDS sees fit (in the same machine will be data-sharing, as the type is not dsh compatible). We'd need to update the readme as well

Please update readme
