tiled_extent Class

A tiled_extent object is an extent object of one to three dimensions that subdivides the extent space into one-, two-, or three-dimensional tiles.

Syntax

template <
    int _Dim0,
    int _Dim1,
    int _Dim2
>
class tiled_extent : public Concurrency::extent<3>;

template <
    int _Dim0,
    int _Dim1
>
class tiled_extent<_Dim0, _Dim1, 0> : public Concurrency::extent<2>;

template <
    int _Dim0
>
class tiled_extent<_Dim0, 0, 0> : public Concurrency::extent<1>;

Parameters

_Dim0
The length of the most significant dimension.

_Dim1
The length of the next-to-most significant dimension.

_Dim2
The length of the least significant dimension.

tiled_extent Constructor

Initializes a new instance of the tiled_extent class.

Syntax

tiled_extent();

tiled_extent(
    const Concurrency::extent<rank>& _Other );

tiled_extent(
    const tiled_extent& _Other );

Parameters

_Other
The extent or tiled_extent object to copy.

get_tile_extent

Returns an extent object that captures the values of the tiled_extent template arguments _Dim0, _Dim1, and _Dim2.

Syntax

Concurrency::extent<rank> get_tile_extent() const restrict(amp,cpu);

Return Value

An extent object that captures the dimensions of this tiled_extent instance.

pad

Returns a new tiled_extent object with extents adjusted up to be evenly divisible by the tile dimensions.

Syntax

tiled_extent pad() const;

Return Value

The new tiled_extent object, by value.

truncate

Returns a new tiled_extent object with extents adjusted down to be evenly divisible by the tile dimensions.

Syntax

tiled_extent truncate() const;

Return Value

Returns a new tiled_extent object with extents adjusted down to be evenly divisible by the tile dimensions.

operator=

Copies the contents of the specified tiled_index object into this one.

Syntax

tiled_extent&  operator= (
    const tiled_extent& _Other ) restrict (amp, cpu);

Parameters

_Other
The tiled_index object to copy from.

Return Value

A reference to this tiled_index instance.

tile_dim0

Stores the length of the most significant dimension.

Syntax

static const int tile_dim0 = _Dim0;

tile_dim1

Stores the length of the next-to-most significant dimension.

Syntax

static const int tile_dim1 = _Dim1;

tile_dim2

Stores the length of the least significant dimension.

Syntax

static const int tile_dim2 = _Dim2;

tile_extent

Gets an extent object that captures the values of the tiled_extent template arguments _Dim0, _Dim1, and _Dim2.

Syntax

__declspec(property(get= get_tile_extent)) Concurrency::extent<rank> tile_extent;
