Check whether parameter is set or not for a ros 2 node
In ROS 2 RCLCPP, is there any way to be sure whether a parameter is set or not for a paricular node ? In ROS 1 , the getParam() function used to do this check.
I found the method SyncParametersClient::has_parameter(const std::string & parameter_name)
inside the parameter_client.hpp code inside rclcpp. Can this ported for AsyncParameters too ?
