class
string_viewA non-owning view of a UTF-8 string.
Base classes
-
template<typename T, size_t Extent = -1>class span<const char>
- A non-owning view of contiguous elements.
Public types
- using const_pointer = const const char*
- Const-qualified pointer to a single element in the span.
- using const_reference = const const char&
- Const-qualified reference to a single element in the span.
- using difference_type = ptrdiff_t
- The difference between two pointers.
- using element_type = const char
- The span's element type.
- using iterator = pointer
- The iterator type returned by begin() and end().
- using pointer = const char*
- Pointer to a single element in the span.
- using reference = const char&
- Reference to a single element in the span.
- using size_type = size_t
- The unsigned integer type used for sizes, indices, et cetera.
- using value_type = api_detail::remove_cv<const char>
- The span's element type without any cv-qualifiers.
Public static variables
Constructors, destructors, conversion operators
- operator bool() const explicit constexpr noexcept
- Returns true if the span's extent is greater than zero and the data pointer is not null.
- operator span<const const char, -1>() const constexpr noexcept
- Casts the span to the const equivalent.
- string_view() defaulted constexpr noexcept
- Default constructor.
-
string_view(const string_
view&) defaulted constexpr noexcept - Copy constructor.
- string_view(const char* str, size_t len) constexpr noexcept
- Pointer + length constructor.
- string_view(const char* str) constexpr noexcept
- Pointer-to-string constructor.
Public functions
- auto back() const -> reference constexpr noexcept
- Returns a reference to the last element in the span.
- auto begin() const -> iterator constexpr noexcept
- Returns an iterator to the first element represented by the span.
- auto data() const -> pointer constexpr noexcept
- Returns a pointer to the first element represented by the span.
- auto empty() const -> bool constexpr noexcept
- Returns true if the span's extent is greater than zero.
- auto end() const -> iterator constexpr noexcept
- Returns an iterator to one-past-the-last element represented by the span.
- auto front() const -> reference constexpr noexcept
- Returns a reference to the first element in the span.
-
auto length() const -> size_
type constexpr noexcept - Returns the number of elements represented by the span.
-
auto operator=(const string_
view&) -> string_ view& defaulted noexcept - Copy-assignment constructor.
-
auto operator[](size_
type idx) const -> reference constexpr noexcept - Returns a reference to an element in the span.
-
auto size() const -> size_
type constexpr noexcept - Returns the number of elements represented by the span.
-
auto size_bytes() const -> size_
type constexpr noexcept - Returns the size of the memory region represented by the span, in bytes.
Compatibility with UE4
- operator::FString() const
