Detailed Description

The mutable MFDataModel::Builder class allows the data model to be constructed incrementally.

Builder is not copyable or movable.

Constructor & Destructor Documentation

◆ Builder()

icu::message2::MFDataModel::Builder::Builder ( UErrorCode & status )

Default constructor.

Returns a Builder with no pattern or selectors set. Either setPattern() or both addSelector() and addVariant() must be called before calling build() on the resulting builder.

Parameters

status Input/output error code.

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

Deprecated:: This API is for technology preview only.

◆ ~Builder()

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

virtual

Destructor.

Member Function Documentation

◆ addBinding()

Builder & icu::message2::MFDataModel::Builder::addBinding	(	Binding &&	b,
		UErrorCode &	status
	)

Adds a binding, There must not already be a binding with the same name.

Parameters

b	The binding. Passed by move.
status	Input/output error code. Set to U_DUPLICATE_DECLARATION_ERROR if `addBinding()` was previously called with a binding with the same variable name as `b`.

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

Deprecated:: This API is for technology preview only.

◆ addSelector()

Builder & icu::message2::MFDataModel::Builder::addSelector	(	Expression &&	selector,
		UErrorCode &	errorCode
	)

noexcept

Adds a selector expression.

Copies expression. If a pattern was previously set, clears the pattern.

Parameters

selector	Expression to add as a selector. Passed by move.
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.

◆ addVariant()

Builder & icu::message2::MFDataModel::Builder::addVariant	(	SelectorKeys &&	keys,
		Pattern &&	pattern,
		UErrorCode &	errorCode
	)

noexcept

Adds a single variant.

If a pattern was previously set using setPattern(), clears the pattern.

Parameters

keys	Keys for the variant. Passed by move.
pattern	Pattern for the variant. Passed by move.
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()

MFDataModel icu::message2::MFDataModel::Builder::build ( UErrorCode & status ) const

noexcept

Constructs a new immutable data model.

If setPattern() has not been called and if addSelector() and addVariant() were not each called at least once, status is set to U_INVALID_STATE_ERROR. If addSelector() was called and addVariant() was never called, or vice versa, then status is set to U_INVALID_STATE_ERROR. Otherwise, either a Pattern or Selectors message is constructed based on the pattern that was previously set, or selectors and variants that were previously set.

The builder object (this) can still be used after calling build().

Parameters

status Input/output error code.

Returns: The new MFDataModel

◆ setPattern()

Builder & icu::message2::MFDataModel::Builder::setPattern ( Pattern && pattern )

Sets the body of the message as a pattern.

If selectors and/or variants were previously set, clears them.

Parameters

pattern Pattern to represent the body of the message. Passed by move.

Returns: A reference to the builder.
