xarray_adaptor

Defined in xtensor/xarray.hpp

template <class EC, layout_type L, class SC>
class xt::xarray_adaptor

Dense multidimensional container adaptor with tensor semantic.

The xarray_adaptor class implements a dense multidimensional container adaptor with tensor semantic. It is used to provide a multidimensional container semantic and a tensor semantic to stl-like containers.

Template Parameters
  • EC: The container type to adapt.
  • L: The layout_type of the adaptor.
  • SC: The type of the containers holding the shape and the strides.

Inherits from xt::xstrided_container< xarray_adaptor< EC, L, SC >, L >, xt::xadaptor_semantic< xarray_adaptor< EC, L, SC > >

Constructors

xarray_adaptor(container_closure_type data)

Constructs an xarray_adaptor of the given stl-like container.

Parameters
  • data: the container to adapt

xarray_adaptor(container_closure_type data, const shape_type &shape, layout_type l = L)

Constructs an xarray_adaptor of the given stl-like container, with the specified shape and layout_type.

Parameters

xarray_adaptor(container_closure_type data, const shape_type &shape, const strides_type &strides)

Constructs an xarray_adaptor of the given stl-like container, with the specified shape and strides.

Parameters

Extended copy semantic

template <class E>
auto operator=(const xexpression<E> &e)

The extended assignment operator.

xadapt (xarray_adaptor)

Defined in xtensor/xadapt.hpp

template <class C, class SC, layout_type L = DEFAULT_LAYOUT>
std::enable_if_t<!detail::is_array< SC >::value, xarray_adaptor<C, L, SC>> xt::xadapt(C &container, const SC &shape, layout_type l = L)

Constructs an xarray_adaptor of the given stl-like container, with the specified shape and layout.

Parameters

template <class C, class SC>
std::enable_if_t<!detail::is_array< SC >::value, xarray_adaptor<C, layout_type::dynamic, SC>> xt::xadapt(C &container, const SC &shape, const SC &strides)

Constructs an xarray_adaptor of the given stl-like container, with the specified shape and strides.

Parameters

template <class P, class O, class SC, layout_type L = DEFAULT_LAYOUT, class A = std::allocator<std::remove_pointer_t<P>>>
std::enable_if_t<!detail::is_array< SC >::value, xarray_adaptor<xbuffer_adaptor<std::remove_pointer_t<P>, O, A>, L, SC>> xt::xadapt(P &pointer, typename A::size_type size, O ownership, const SC &shape, layout_type l = L, const A &alloc = A())

Constructs an xarray_adaptor of the given dynamically allocated C array, with the specified shape and layout.

Parameters
  • pointer: the pointer to the beginning of the dynamic array
  • size: the size of the dynamic array
  • ownership: indicates whether the adaptor takes ownership of the array. Possible values are no_ownerhsip() or accept_ownership()
  • shape: the shape of the xarray_adaptor
  • l: the layout_type of the xarray_adaptor
  • alloc: the allocator used for allocating / deallocating the dynamic array

Constructs an xarray_adaptor of the given dynamically allocated C array, with the specified shape and layout.

Parameters
  • pointer: the pointer to the beginning of the dynamic array
  • size: the size of the dynamic array
  • ownership: indicates whether the adaptor takes ownership of the array. Possible values are no_ownerhsip() or accept_ownership()
  • shape: the shape of the xarray_adaptor
