Detailed Description

A C++ "range" for iterating over all of the elements of a USet.

Convenient all-in one iteration, but creates a std::u16string for each code point or string.

Code points are returned first, then empty and multi-character strings.

using U_HEADER_NESTED_NAMESPACE::USetElements;
LocalUSetPointer uset(uset_openPattern(u"[abcçカ🚴{}{abc}{de}]", -1, &errorCode));
for (auto el : USetElements(uset.getAlias())) {
    int32_t len32 = el.length();
    char utf8[200];
    u_strToUTF8WithSub(utf8, int32_t{sizeof(utf8) - 1}, nullptr,
                       el.data(), len32, 0xFFFD, nullptr, errorCode);
    printf("uset.element length %ld \"%s\"\n", long{len32}, utf8);
}

C++ UnicodeSet has member functions for iteration, including begin() and end().

Returns

an all-elements iterator.
