michael@0:  Assumptions:
michael@0: 
michael@0:  The attribute currentValue will throw an exception
michael@0:  if it cannot be set i.e. if the value is not a
michael@0:  member of the interval.
michael@0:  This may not be the 'desired' behaviour given gObject
michael@0:  equivalent. Thus it could be changed to be:
michael@0: 
michael@0:  readonly attribute double currentValue;
michael@0:  boolean setCurrentValue (double long value);
michael@0: 
michael@0:  GValue can represent many basic types.
michael@0:  Since this interface is designed to represent
michael@0:  an interval and a member of double should
michael@0:  cover the cases of char int and float.
