Hi,

I'd like to use the tfMessage - defined in the tf package. It contains
an array of geometry_msgs/TransformStamped elements.
How do I fill this in C++?
I tried to make a new tf::tfMessage tfFrames, but I'm stuck on
accessing the elements. I was wondering whether someone can provide me
an example on how to work with messages containing arrays?
The ROS wiki says I have to use the uint32 prefix and std::vector but
I don't see how to do this.
