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