/**
 * <code>LocaleBuilder</code> is used to build instances of <code>Locale</code>
 * from values configured by the setters. Unlike the <code>Locale</code>
 * constructors, the <code>LocaleBuilder</code> checks if a value configured by a
 * setter satisfies the syntax requirements defined by the <code>Locale</code>
 * class. A <code>Locale</code> object created by a <code>LocaleBuilder</code> is
 * well-formed and can be transformed to a well-formed IETF BCP 47 language tag
 * without losing information.
 *
 * The following example shows how to create a <code>Locale</code> object
 * with the <code>LocaleBuilder</code>.
 * <blockquote>
 * <pre>
 * UErrorCode status = U_ZERO_ERROR;
 * Locale aLocale = LocaleBuilder()
 * .setLanguage("sr")
 * .setScript("Latn")
 * .setRegion("RS")
 * .build(status);
 * if (U_SUCCESS(status)) {
 * // ...
 * }
 * </pre>
 * </blockquote>
 *
 * LocaleBuilders can be reused; <code>clear()</code> resets all
 * fields to their default values.
 *
 * LocaleBuilder tracks errors in an internal UErrorCode. For all setters,
 * except setLanguageTag and setLocale, LocaleBuilder will return immediately
 * if the internal UErrorCode is in error state.
 * To reset internal state and error code, call clear method.
 * The setLanguageTag and setLocale method will first clear the internal
 * UErrorCode, then track the error of the validation of the input parameter
 * into the internal UErrorCode.
