Detailed Description

template<sycl::access::mode access_mode>
class stencil::tiling::Grid< Cell, tile_width, tile_height, halo_radius >::GridAccessor< access_mode >

An accessor for the monotile grid.

Instances of this class provide access to a grid, so that host code can read and write the contents of a grid. As such, it fullfils the GridAccessor concept.

Template Parameters

access_mode

The access mode for the accessor.

operator[]() [1/3]

template<typename Cell , uindex_t tile_width = 1024, uindex_t tile_height = 1024, uindex_t halo_radius = 1>

template<sycl::access::mode access_mode>

Cell const & stencil::tiling::Grid< Cell, tile_width, tile_height, halo_radius >::GridAccessor< access_mode >::operator[] ( sycl::id< 2 >  id )

inline

Access a cell of the grid.

Parameters

id	The index of the accessed cell. The first index is the column index, the second one is the row index.

Returns

A constant reference to the indexed cell.

operator[]() [2/3]

template<typename Cell , uindex_t tile_width = 1024, uindex_t tile_height = 1024, uindex_t halo_radius = 1>

template<sycl::access::mode access_mode>

Cell & stencil::tiling::Grid< Cell, tile_width, tile_height, halo_radius >::GridAccessor< access_mode >::operator[] ( sycl::id< 2 >  id )

inline

Access a cell of the grid.

Parameters

id	The index of the accessed cell. The first index is the column index, the second one is the row index.

Returns

A reference to the indexed cell.

operator[]() [3/3]

template<typename Cell , uindex_t tile_width = 1024, uindex_t tile_height = 1024, uindex_t halo_radius = 1>

template<sycl::access::mode access_mode>

BaseSubscript stencil::tiling::Grid< Cell, tile_width, tile_height, halo_radius >::GridAccessor< access_mode >::operator[] ( uindex_t  i )

inline

Access/Dereference the first dimension.

This subscript operator is the first subscript in an expression like accessor[i_column][i_row]. It will return a BaseSubscript object that handles subsequent dimensions.
