/**
 * <code>ULocaleBuilder</code> is used to build valid <code>locale</code> id
 * string or IETF BCP 47 language tag from values configured by the setters.
 * The <code>ULocaleBuilder</code> checks if a value configured by a
 * setter satisfies the syntax requirements defined by the <code>Locale</code>
 * class. A string of Locale created by a <code>ULocaleBuilder</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> string
 * with the <code>ULocaleBuilder</code>.
 * <blockquote>
 * <pre>
 * UErrorCode err = U_ZERO_ERROR;
 * char buffer[ULOC_FULLNAME_CAPACITY];
 * ULocaleBuilder* builder = ulocbld_open();
 * ulocbld_setLanguage(builder, "sr", -1);
 * ulocbld_setScript(builder, "Latn", -1);
 * ulocbld_setRegion(builder, "RS", -1);
 * int32_t length = ulocbld_buildLocaleID(
 * builder, buffer, ULOC_FULLNAME_CAPACITY, &error);
 * ulocbld_close(builder);
 * </pre>
 * </blockquote>
 *
 * ULocaleBuilders can be reused; <code>ulocbld_clear()</code> resets all
 * fields to their default values.
 *
 * ULocaleBuilder tracks errors in an internal UErrorCode. For all setters,
 * except ulocbld_setLanguageTag and ulocbld_setLocale, ULocaleBuilder will return immediately
 * if the internal UErrorCode is in error state.
 * To reset internal state and error code, call clear method.
 * The ulocbld_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.
