/**
 * 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.
 *
 * <p>See UFormattable for a C wrapper.
