          :return:    Returns a dictionary containing the parameter intervals, using the parameter
              name as key, while the value hast the following format:
              [minValue, maxValue, minIntervalClosed, maxIntervalClosed]
  
                  - minValue
                      Minimal value for the parameter
                  - maxValue
                      Maximal value for the parameter
                  - minIntervalClosed
                      :py:const:`True`, if minValue represents a valid value for the parameter.
                      :py:const:`False` otherwise.
                  - maxIntervalClosed:
                      :py:const:`True`, if maxValue represents a valid value for the parameter.
                      :py:const:`False` otherwise.
