## Constructor & Destructor Documentation

## Builder()

icu::message2::data_model::Operator::Builder::Builder | ( | UErrorCode & | status | ) |

Default constructor.

Returns a Builder with no function name or options 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::Operator::Builder::~Builder | ( |  | ) |

virtual

Destructor.

## Member Function Documentation

## addOption()

Builder & icu::message2::data_model::Operator::Builder::addOption | ( | const UnicodeString & | key,
|  | Operand && | value,
|  | UErrorCode & | status
| ) |  |

noexcept

Sets this operator to be a function annotation and adds a single option.

Parameters

  key | The name of the option.
  value | The value (right-hand side) of the option.
  status | Input/output error code.

Returns
  A reference to the builder.

## build()

Operator icu::message2::data_model::Operator::Builder::build | ( | UErrorCode & | status | ) |

Constructs a new immutable `Operator` using the function name and options that were previously set.

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 Operator

## setFunctionName()

Builder & icu::message2::data_model::Operator::Builder::setFunctionName | ( | FunctionName && | func | ) |

Sets this operator to be a function annotation and sets its name to `func`.

Parameters

  func | The function name.

Returns
  A reference to the builder.
