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::distr_queue::fence.

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
