In some of the source files in the navigation stack, there are classes that uses multiple nodehandles, that are usually called nh and private_nh. They are of the same type ros::NodeHandle, so in what sense are the handle called private_nh private?
They are initialised such that they will resolve names in the private namespace of the Node. See wiki/roscpp/Overview/NodeHandles and wiki/Names.
From http://wiki.ros.org/Names : "In general, resources can create resources within their namespace and they can access resources within or above their own namespace"
Does this mean that it is impossible for another node to subscribe to any topic being published using the private nodehandle?
