  52  Assumptions:
  53
  54  The attribute currentValue will throw an exception
  55  if it cannot be set i.e. if the value is not a
  56  member of the interval.
  57  This may not be the 'desired' behaviour given gObject
  58  equivalent. Thus it could be changed to be:
  59
  60  readonly attribute double currentValue;
  61  boolean setCurrentValue (double long value);
  62
  63  GValue can represent many basic types.
  64  Since this interface is designed to represent
  65  an interval and a member of double should
  66  cover the cases of char int and float.
