Class NumberFormat.NumberFormatFactory

java.lang.Object

com.ibm.icu.text.NumberFormat.NumberFormatFactory

Direct Known Subclasses:

NumberFormat.SimpleNumberFormatFactory

Enclosing class:

NumberFormat

public abstract static class NumberFormat.NumberFormatFactory
extends Object

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 locales already supported by ICU.

Note: as of ICU4J 3.2, the default API for NumberFormatFactory uses ULocale instead of Locale. Instead of overriding createFormat(Locale, int), new implementations should override createFactory(ULocale, int). Note that one of these two methods MUST be overridden or else an infinite loop will occur.

Method Detail

visible

public boolean visible()

Returns true if this factory is visible. Default is true. If not visible, the locales supported by this factory will not be listed by getAvailableLocales. This value must not change.

Returns:

true if the factory is visible.

getSupportedLocaleNames

public abstract Set<String> getSupportedLocaleNames()

Returns an immutable collection of the locale names directly supported by this factory.

Returns:

the supported locale names.

createFormat

public NumberFormat createFormat(ULocale loc,
                                 int formatType)

Returns 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. Note: as of ICU4J 3.2, implementations should override this method instead of createFormat(Locale, int).

Parameters:

loc - the locale for which to create the format

formatType - the type of format

Returns:

the NumberFormat, or null.

createFormat

public NumberFormat createFormat(Locale loc,
                                 int formatType)

Returns 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. Note: as of ICU4J 3.2, createFormat(ULocale, int) should be overridden instead of this method. This method is no longer abstract and delegates to that method.

Parameters:

loc - the locale for which to create the format

formatType - the type of format

Returns:

the NumberFormat, or null.
