◆ Builder()

icu::message2::MFFunctionRegistry::Builder::Builder ( UErrorCode & errorCode )

Deprecated:: This API is for technology preview only.

◆ ~Builder()

virtual icu::message2::MFFunctionRegistry::Builder::~Builder ( )

Member Function Documentation

◆ adoptFormatter()

Builder & icu::message2::MFFunctionRegistry::Builder::adoptFormatter	(	const data_model::FunctionName &	formatterName,
		FormatterFactory *	formatterFactory,
		UErrorCode &	errorCode
	)

Registers a formatter factory to a given formatter name.

Parameters

formatterName	Name of the formatter being registered.
formatterFactory	A pointer to a FormatterFactory object to use for creating `formatterName` formatters. This argument is adopted.
errorCode	Input/output error code

Returns: A reference to the builder.

Internal:: Do not use. This API is for internal use only. ICU 75 technology preview

Deprecated:: This API is for technology preview only.

◆ adoptSelector()

Builder & icu::message2::MFFunctionRegistry::Builder::adoptSelector	(	const data_model::FunctionName &	selectorName,
		SelectorFactory *	selectorFactory,
		UErrorCode &	errorCode
	)

Registers a selector factory to a given selector name.

Adopts selectorFactory.

Parameters

selectorName	Name of the selector being registered.
selectorFactory	A SelectorFactory object to use for creating `selectorName` selectors.
errorCode	Input/output error code

Returns: A reference to the builder.

Internal:: Do not use. This API is for internal use only. ICU 75 technology preview

Deprecated:: This API is for technology preview only.

◆ build()

MFFunctionRegistry icu::message2::MFFunctionRegistry::Builder::build ( )

Creates an immutable MFFunctionRegistry object with the selectors and formatters that were previously registered.

The builder cannot be used after this call. The build() method is destructive to avoid the need for a deep copy of the FormatterFactory and SelectorFactory objects (this would be necessary because FormatterFactory can have mutable state), which in turn would require implementors of those interfaces to implement a clone() method.

Returns: The new MFFunctionRegistry

Internal:: Do not use. This API is for internal use only. ICU 75 technology preview

Deprecated:: This API is for technology preview only.

◆ setDefaultFormatterNameByType()

Builder & icu::message2::MFFunctionRegistry::Builder::setDefaultFormatterNameByType	(	const UnicodeString &	type,
		const data_model::FunctionName &	functionName,
		UErrorCode &	errorCode
	)

Registers a formatter factory to a given type tag.

(See FormattableObject for details on type tags.)

Parameters

type	Tag for objects to be formatted with this formatter.
functionName	A reference to the name of the function to use for creating formatters for `formatterType` objects.
errorCode	Input/output error code

Returns: A reference to the builder.
