-/**
- * Formattable objects can be passed to the Format class or
- * its subclasses for formatting.  Formattable is a thin wrapper
- * class which interconverts between the primitive numeric types
- * (double, long, etc.) as well as UDate and UnicodeString.
- *
- * <p>Internally, a Formattable object is a union of primitive types.
- * As such, it can only store one flavor of data at a time.  To
- * determine what flavor of data it contains, use the getType method.
- *
- * <p>As of ICU 3.0, Formattable may also wrap a UObject pointer,
- * which it owns.  This allows an instance of any ICU class to be
- * encapsulated in a Formattable.  For legacy reasons and for
- * efficiency, primitive numeric types are still stored directly
- * within a Formattable.
- *
- * <p>The Formattable class is not suitable for subclassing.
