explicit MultiThreadedExecutor(const rclcpp::ExecutorOptions &options = rclcpp::ExecutorOptions(), size_t number_of_threads = 0, bool yield_before_execute = false, std::chrono::nanoseconds timeout = std::chrono::nanoseconds(-1))
Constructor for MultiThreadedExecutor.
For the yield_before_execute option, when true std::this_thread::yield() will be called after acquiring work (as an AnyExecutable) and releasing the spinning lock, but before executing the work. This is useful for reproducing some bugs related to taking work more than once.
- Parameters:
options – common options for all executors
number_of_threads – number of threads to have in the thread pool, the default 0 will use the number of cpu cores found instead
yield_before_execute – if true std::this_thread::yield() is called
timeout – maximum time to wait

virtual ~MultiThreadedExecutor()
-
virtual void spin() override

- Throws:
std::runtime_error – when spin() called while already spinning
