Detailed Description

template<class D>
class lin::internal::Base< D >

Value backed tensor interface with resizing support.

Template Parameters

D	Derived type.

This is the third of the three main entry points on the lin inheritance tree after internal::Mapping.

Here, direct tracking of runtime dimensions and the ability to resize is added. A getter to retrive a pointer to the element backing array is also included.

The main purpose is to provide an interface that supports value backed types

• i.e. those directly storing tensor elements in a member array or and a pointer.

Member Function Documentation

template<class D>

constexpr Traits::elem_t* lin::internal::Base< D >::data ( )

inline

Retrives a pointer to the element backing array.

Returns

Pointer to the backing array.

The elements of the tensor are layed out in row major order in the backing array. They are stored contiguously in memory.

template<class D>

constexpr Traits::elem_t const* lin::internal::Base< D >::data ( ) const

inline

Retrives a constant pointer to the element backing array.

Returns

Constant pointer to the backing array.

The elements of the tensor are layed out in row major order in the backing array. They are stored contiguously in memory.

template<class D>

constexpr Traits::elem_t& lin::internal::Base< D >::operator() ( size_t  i, size_t  j  )

inline

Provides read and write access to tensor elements.

Parameters

i	Row index.
j	Column index.

Returns

Reference to the tensor element.

If the indices are out of bounds as defined by the tensor's current dimensions, lin assertion errors will be triggered.

template<class D>

constexpr Traits::elem_t& lin::internal::Base< D >::operator() ( size_t  i )

inline

Provides read and write access to tensor elements.

Parameters

i

Index

Returns

Reference to the tensor element.

Element access proceeds as if all the elements of the tensor stream were flattened into an array in row major order.

If the index is out of bounds as defined by the tensor's current size, lin lin assertion errors will be triggered.
