How to get information from the navfn planner execution
Hi everybody! I'm working on a A.I. project and I need to know how to obtain information from the navfn global planner during execution. In more details, what should I do in order to call the methods listed in the navfn::NavFn class reference (http://www.ros.org/doc/api/navfn/html/classnavfn_1_1NavFn.html#a991e667731691eb111cddc786e2d02d0) to retrieve run-time informations and can later work with them? The information I need is the one returned by getLastPathCost().
Any suggestion would help. Thanks!
