| def swri_rospy.service_wrapper | ( | func | ) |
This is a decorator for functions that handle ROS service calls. It catches unhandled exceptions and reports them cleanly as errors on the ROS console.

| def swri_rospy.single_threaded | ( | callback | ) |
This decorator can be used on service or subscriber callbacks. A callback wrapped with this decorator will put a condition on the callback_queue and then wait its turn before executing the decorated callback.

| def swri_rospy.spin | ( | ) |
This spinner is used in place of the rospy.spin() method. Whereas rospy.spin() simply waits for rospy.is_shutdown(), this spinner processes the callback queue until rospy.is_shutdown() is true. The callback queue is thread-safe, so for a multi-threaded queue processor, call this spin method in multiple threads.
