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:

- Deprecated:
- This API is for technology preview only.
◆ ~Builder()

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 75.0 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.

◆ 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.

◆ 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 75.0 technology preview
