  19  Assumptions:
  20
  21  The attribute currentValue will throw an exception
  22  if it cannot be set i.e. if the value is not a
  23  member of the interval.
  24  This may not be the 'desired' behaviour given gObject
  25  equivalent. Thus it could be changed to be:
  26
  27  readonly attribute double currentValue;
  28  boolean setCurrentValue (double long value);
  29
  30  GValue can represent many basic types.
  31  Since this interface is designed to represent
  32  an interval and a member of double should
  33  cover the cases of char int and float.
