I wrote a while loop and I want to change loop rates while running. The problem is , ros::Rate can only set frequency in constructor. After creating the object I can not change frequency.

How can I handle this problem.

Any help will be appreciated..

Would constructing a new one and assigning it to the same variable not work?

I have 4 different loop_freq changing according to some conditions. will I create 4 different ros::Rate objects?

 ros::Rate loop_rate(loop_freq);
  while (ros::ok()){
        //do some work
        loop_freq= getLoopRate(); // loop_freq changes
