Hi! Does anyone have a quick example on how to retrieve lists from the parameter server? Suppose I want to store sets of values (any amount) in parameters. Does the param file look correct like this? ---- coords/x: [0.0, 0.0, 0.2, 0.15] coords/y: [0.0, 0.1, 0.0, 0.1] coords/theta: [0.0, 0.0, -0.1, 0.1] ---- I would then retrieve the three lists, check if they are of the same length, and create n (=4 here) tuples of out of them. Is there any documentation available on how to retrieve these lists in roscpp? http://www.ros.org/wiki/roscpp/Overview/Parameter%20Server points to http://xmlrpcpp.sourceforge.net/doc/classXmlRpc_1_1XmlRpcValue.html for lists, but a quick example (or a pointer to how it is used in another ROS node) would be nice to get started.
