class buffer_snapshot

Declaration

template <typename T, int Dims>
class buffer_snapshot { /* full declaration omitted */ };

Description

Owned representation of buffer contents as captured by celerity::queue::fence.

Declared at: include/fence.h:30

Template Parameters

T

int Dims

Member Variables

subrange<Dims> m_subrange

std::unique_ptr<T[]> m_data

Member Function Overview

• buffer_snapshot()
• buffer_snapshot(buffer_snapshot<T, Dims> && other) noexcept
• get_data() const → const T *
• get_offset() const → id<Dims>
• get_range() const → range<Dims>
• get_subrange() const → subrange<Dims>
• template <int D = Dims, std::enable_if_t<D == 0, int> = 0>
  operator*() const → const T &
• operator=(buffer_snapshot<T, Dims> && other) noexcept → buffer_snapshot<T, Dims> &
• operator[](id<Dims> index) const → const T &
• template <int D = Dims, std::enable_if_t<(D > 0), int> = 0>
  operator[](size_t index) const → decltype(auto)
• buffer_snapshot(subrange<Dims> sr, std::unique_ptr<T[]> data) → explicit
