Public Member Functions inherited from ros_control_boilerplate::GenericHWInterface
virtual bool	canSwitch (const std::list< hardware_interface::ControllerInfo > &start_list, const std::list< hardware_interface::ControllerInfo > &stop_list) const
	Check (in non-realtime) if given controllers could be started and stopped from the current state of the RobotHW with regard to necessary hardware interface switches. Start and stop list are disjoint. This is just a check, the actual switch is done in doSwitch() More...
