Struct Documentation

struct ripple::BlockExtractor

This struct extracts the blocks from a tensor.

Public Types

template<typename T>
using NotModifierOrSharedOrTensorEnable = std::enable_if_t<!is_modifier_v<T> && !is_shared_wrapper_v<T> && !is_tensor_v<T>, int>

Defines a valid enable if not a modifier, shared wrapper, or tensor.

Template Parameters

• T: The type to base the enable on.

Public Static Functions

template<typename T, NotModifierOrSharedOrTensorEnable<T> = 0>
auto extract_blocks_if_tensor(T &&t) noexcept -> T&&

Extracts the blocks from a tensor.

Note

This overload is for non tensor types and simply forward the given type.

Return

An rvalue rerence to the object.

Parameters

• t: The object to extract the blocks from.

Template Parameters

• T: The type of the object.

template<typename T, tensor_enable_t<T> = 0>
auto extract_blocks_if_tensor(T &t) noexcept -> std::remove_reference_t<decltype(t.blocks_)>&

Extracts the blocks from a tensor.

Note

This overload is for tensor types and returns a reference to the blocks which define the tensor.

Return

An reference to the tensor blocks.

Parameters

• t: The tensor object to extract the blocks from.

Template Parameters

• T: The type of the tensor object.

template<typename T, Modifier M, tensor_enable_t<T> = 0>
auto extract_blocks_if_tensor(const ModificationSpecifier<T, M> &specifier) noexcept

Extracts the blocks from a tensor.

Note

This overload is for tensor types wrapped in a modification specifier and returns a reference to blocks, rewrapped in the specifier.

Return

A new modification specifier which references the tensor blocks.

Parameters

• specifier: The modification specifier to extract the blocks from.

Template Parameters

• T: The type of the tensor object. \tparmam M The type of the modification.

template<typename T, tensor_enable_t<T> = 0>
auto extract_blocks_if_tensor(const SharedWrapper<T> &wrapper) noexcept

Extracts the blocks from a tensor.

Note

This overload is for tensor types wrapped in a shared wrapper and returns a reference to blocks, rewrapped in the wrapper. specifier.

Return

A new shared wrapper which references the tensor blocks.

Parameters

• wrapper: The shared wrapper to extract the blocks from.

Template Parameters

• T: The type of the tensor object.

template<typename T, tensor_enable_t<T> = 0>
auto extract_blocks_if_tensor(const ExpansionWrapper<T> &wrapper) noexcept

Extracts the blocks from a tensor.

Note

This overload is for tensor types wrapped in a shared wrapper and returns a reference to blocks, rewrapped in the wrapper. specifier.

Return

A new shared wrapper which references the tensor blocks.

Parameters

• wrapper: The shared wrapper to extract the blocks from.

Template Parameters

• T: The type of the tensor object.
