Hello ROS users.
For an application I'm writing I need message introspection. This means
given the name and type of a topic (from a config or user input), I want
to open it in a generic way, i.e. similar to how rosbag record does it.
But instead of requiring only the binary blob for storage, I would like
to be able to iterate over the message in a key/value pair fashion.
To get a good efficiency out of it, I would like to do this with C++.
Does someone know a way to achieve this? I looked through the code but I
couldn't see anything that would allow this, so I hope I'm just missing
something. Can someone point me into the right direction?
I know this is easy with Python and Lua, and I'm doing that for now, but
I would like to have the option to do this in C++ when the need for
extra performance arises.
Thanks for your time,
Tim
