Detailed Description

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.

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.

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.

The Formattable class is not suitable for subclassing.

See UFormattable for a C wrapper.

Member Enumeration Documentation

◆ ISDATE

This enum is only used to let callers distinguish between the Formattable(UDate) constructor and the Formattable(double) constructor; the compiler cannot distinguish the signatures, since UDate is currently typedefed to be either double or long.

If UDate is changed later to be a bonafide class or struct, then we no longer need this enum.
