Builder& icu::message2::data_model::Pattern::Builder::add | ( | Markup && | part,
|  | UErrorCode & | status
| ) |  |
| noexcept

Adds a single markup part to the pattern.

## ◆ add() [3/3]

Builder& icu::message2::data_model::Pattern::Builder::add | ( | UnicodeString && | part,
|  | UErrorCode & | status
| ) |  |
| noexcept

Adds a single text part to the pattern.

Copies `part`.

## ◆ build()

Pattern icu::message2::data_model::Pattern::Builder::build | ( | UErrorCode & | status | ) | const
| noexcept

Constructs a new immutable `Pattern` using the list of parts set with previous `add()` calls.

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

Parameters

  status | Input/output error code.

Returns
  The pattern object
