    • incrementThrottleCount

      public void incrementThrottleCount()
      This method increments a counter that is used to control the throttling of a connection. The connection's read operations are paused when the counter's value is greater than 0, indicating that throttling is in effect. It's important to note that after calling this method, it is the caller's responsibility to ensure that the counter is decremented by calling the decrementThrottleCount() method when throttling is no longer needed on the connection.

    • decrementThrottleCount

      public void decrementThrottleCount()
      This method decrements a counter that is used to control the throttling of a connection. The connection's read operations are resumed when the counter's value is 0, indicating that throttling is no longer in effect. It's important to note that before calling this method, the caller should have previously incremented the counter by calling the incrementThrottleCount() method when throttling was needed on the connection.
