Detailed Description

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

Convenient all-in one iteration, but creates a UnicodeString 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())) {
    std::string u8;
    printf("uset.string length %ld \"%s\"\n", (long)el.length(), el.toUTF8String(u8).c_str());
}

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

Returns

an all-elements iterator.
