Detailed Description

template<typename T, oiio_span_size_type Extent = dynamic_extent>
class span_strided< T, Extent >

span_strided<T> : a non-owning, mutable reference to a contiguous array with known length and optionally non-default strides through the data. An span_strided<T> is mutable (the values in the array may be modified), whereas an span_strided<const T> is not mutable.

Constructor & Destructor Documentation

template<typename T, oiio_span_size_type Extent = dynamic_extent>
constexpr span_strided< T, Extent >::span_strided ( )
inlinenoexcept

Default ctr – points to nothing.

Definition at line 275 of file span.h.

template<typename T, oiio_span_size_type Extent = dynamic_extent>
constexpr span_strided< T, Extent >::span_strided ( const span_strided< T, Extent > &  copy)
inline

Copy constructor.

Definition at line 278 of file span.h.

template<typename T, oiio_span_size_type Extent = dynamic_extent>
constexpr span_strided< T, Extent >::span_strided ( pointer  data,
size_type  size,
stride_type  stride = 1 
)
inline

Construct from T* and size, and optionally stride.

Definition at line 282 of file span.h.

template<typename T, oiio_span_size_type Extent = dynamic_extent>
constexpr span_strided< T, Extent >::span_strided ( T &  data)
inline

Construct from a single T&.

Definition at line 286 of file span.h.

template<typename T, oiio_span_size_type Extent = dynamic_extent>
template<size_t N>
constexpr span_strided< T, Extent >::span_strided ( T(&)  data[N])
inline

Construct from a fixed-length C array. Template magic automatically finds the length from the declared type of the array.

template<typename T, oiio_span_size_type Extent = dynamic_extent>
template<class Allocator >
OIIO_CONSTEXPR14 span_strided< T, Extent >::span_strided ( std::vector< T, Allocator > &  v)
inline

Construct from std::vector<T>.

Definition at line 295 of file span.h.

template<typename T, oiio_span_size_type Extent = dynamic_extent>
template<class Allocator >
constexpr span_strided< T, Extent >::span_strided ( const std::vector< value_type, Allocator > &  v)
inline

Construct from const std::vector<T>. This turns const std::vector<T> into an span_strided<const T> (the span_strided isn't const, but the data it points to will be).

template<typename T, oiio_span_size_type Extent = dynamic_extent>
constexpr span_strided< T, Extent >::span_strided ( std::initializer_list< T >  il)
inline

Construct an span from an initializer_list.

Definition at line 306 of file span.h.

template<typename T, oiio_span_size_type Extent = dynamic_extent>
constexpr span_strided< T, Extent >::span_strided ( span< T >  av)
inline

Initialize from an span (stride will be 1).
