Constructor & Destructor Documentation

Builder()

icu::message2::data_model::Expression::Builder::Builder

(

UErrorCode &

status

)

Default constructor.

Returns a Builder with no operator or operand set.

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::data_model::Expression::Builder::~Builder ( )

virtual

Destructor.

Internal:

Member Function Documentation

addAttribute()

Builder& icu::message2::data_model::Expression::Builder::addAttribute	(	const UnicodeString &	key,
		Operand &&	value,
		UErrorCode &	status
	)

Adds a single attribute.

Parameters

key	The name of the attribute.
value	The value (right-hand side) of the attribute.
status	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()

Expression icu::message2::data_model::Expression::Builder::build

(

UErrorCode &

status

)

Constructs a new immutable Expression using the operand and operator that were previously set.

If neither setOperand() nor setOperator() was previously called, or if setOperand() was called with the null operand and setOperator() was never called, then status is set to U_INVALID_STATE_ERROR.

The builder object (this) can still be used after calling build(). The build() method is non-const for internal implementation reasons, but is observably const.

Parameters

status

Input/output error code.

Returns

The new Expression.

Internal:

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

Deprecated:

This API is for technology preview only.

setOperand()

Builder& icu::message2::data_model::Expression::Builder::setOperand

(

Operand &&

rAnd

)

Sets the operand of this expression.

Parameters

rAnd	The operand to set. Passed by move.

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.

setOperator()

Builder& icu::message2::data_model::Expression::Builder::setOperator

(

Operator &&

rAtor

)

Sets the operator of this expression.

Parameters

rAtor

The operator to set. Passed by move.

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.
