## Detailed Description

A NumberFormatFactory is used to register new number formats.

The factory should be able to create any of the predefined formats for each locale it supports. When registered, the locales it supports extend or override the locale already supported by ICU.

## ◆ createFormat()

virtual NumberFormat * icu::NumberFormatFactory::createFormat | ( | const Locale & | loc,
|  | UNumberFormatStyle | formatType )
| pure virtual

## ◆ getSupportedIDs()

virtual const UnicodeString * icu::NumberFormatFactory::getSupportedIDs | ( | int32_t & | count,
|  | UErrorCode & | status ) const
| pure virtual

Return the locale names directly supported by this factory.

The number of names is returned in count;
