Detailed Description
template<typename CP32, typename UnitIter, typename = void>
class U_HEADER_ONLY_NAMESPACE::UnsafeCodeUnits< CP32, UnitIter, typename >
class U_HEADER_ONLY_NAMESPACE::UnsafeCodeUnits< CP32, UnitIter, typename >
Result of decoding a code unit sequence for one code point.
Returned from non-validating Unicode string code point iterators. Base class for class CodeUnits which is returned from validating iterators.
- Template Parameters
-
CP32 Code point type: UChar32 (=int32_t) or char32_t or uint32_t; should be signed if UTF_BEHAVIOR_NEGATIVE UnitIter An iterator (often a pointer) that returns a code unit type: UTF-8: char or char8_t or uint8_t; UTF-16: char16_t or uint16_t or (on Windows) wchar_t; UTF-32: char32_t or UChar32=int32_t or (on Linux) wchar_t

Member Function Documentation
◆ begin()
template<typename CP32, typename UnitIter, typename = void>
|
inline |
- Returns
- the start of the code unit sequence for one code point. Only enabled if UnitIter is a (multi-pass) forward_iterator or better.

Definition at line 394 of file utfiterator.h.
◆ codePoint()
template<typename CP32, typename UnitIter, typename = void>
|
inline |
- Returns
- the Unicode code point decoded from the code unit sequence. If the sequence is ill-formed and the iterator validates, then this is a replacement value according to the iterator‘s UTFIllFormedBehavior template parameter.

◆ end()
template<typename CP32, typename UnitIter, typename = void>

- Returns
- the limit (exclusive end) of the code unit sequence for one code point. Only enabled if UnitIter is a (multi-pass) forward_iterator or better.

◆ length()
template<typename CP32, typename UnitIter, typename = void>

- Returns
- the length of the code unit sequence for one code point.

◆ stringView()
template<typename CP32, typename UnitIter, typename = void>
template<typename Iter = UnitIter, typename Unit = typename std::iterator_traits<Iter>::value_type>
|

- Returns
- a string_view of the code unit sequence for one code point. Only works if UnitIter is a pointer or a contiguous_iterator.
