## 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.

## Constructor & Destructor Documentation

## ~NumberFormatFactory()

virtual icu::NumberFormatFactory::~NumberFormatFactory | ( |  | ) |

virtual

Destructor.

Stable:
  ICU 3.0

## Member Function Documentation

## createFormat()

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

pure virtual

Return a number format of the appropriate type.

If the locale is not supported, return null. If the locale is supported, but the type is not provided by this service, return null. Otherwise return an appropriate instance of NumberFormat.

Stable:
  ICU 2.6

## 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;

Stable:
  ICU 2.6

Implemented in icu::SimpleNumberFormatFactory.

## visible()

virtual UBool icu::NumberFormatFactory::visible | ( |  | ) | const

pure virtual

Return true if this factory will be visible.

Default is true. If not visible, the locales supported by this factory will not be listed by getAvailableLocales.

Stable:
  ICU 2.6

Implemented in icu::SimpleNumberFormatFactory.
