class USetElements

Defined at line 1875 of file ../../third_party/icu/latest/source/common/unicode/uset.h

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.

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

Returns

an all-elements iterator.
