Detailed Description

Formattable objects can be passed to theFormat 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 andUnicodeString.

Internally, aFormattable 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 aUObject pointer, which it owns. This allows an instance of any ICU class to be encapsulated in aFormattable. For legacy reasons and for efficiency, primitive numeric types are still stored directly within aFormattable.

TheFormattable class is not suitable for subclassing.

See UFormattable for a C wrapper.

Member Enumeration Documentation

◆ ISDATE

enumicu::Formattable::ISDATE

This enum is only used to let callers distinguish between theFormattable(UDate) constructor and theFormattable(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.

Stable:: ICU 2.4

Definition at line74 of filefmtable.h.

◆ Type

enumicu::Formattable::Type

Selector for flavor of data type contained within aFormattable object.

Formattable is a union of several different types, and at any time contains exactly one type.

Stable:: ICU 2.4

Enumerator
kDate	Selector indicating a UDate value. Use getDate to retrieve the value. Stable: ICU 2.4
kDouble	Selector indicating a double value. Use getDouble to retrieve the value. Stable: ICU 2.4
kLong	Selector indicating a 32-bit integer value. Use getLong to retrieve the value. Stable: ICU 2.4
kString	Selector indicating aUnicodeString value. Use getString to retrieve the value. Stable: ICU 2.4
kArray	Selector indicating an array of Formattables. Use getArray to retrieve the value. Stable: ICU 2.4
