Detailed Description

template<int D0, int D1>
class Concurrency::tiled_extent< D0, D1, 0 >

Represents an extent subdivided into 1-, 2-, or 3-dimensional tiles.

Template Parameters

D0,D1,D2 The length of the tile in each specified dimension, where D0 is the most-significant dimension and D2 is the least-significant.

Constructor & Destructor Documentation

template<int D0, int D1>

Concurrency::tiled_extent< D0, D1, 0 >::tiled_extent ( )

inline

Default constructor.

The origin and extent is default-constructed and thus zero.

template<int D0, int D1>

Concurrency::tiled_extent< D0, D1, 0 >::tiled_extent ( const tiled_extent< D0, D1, 0 > & other )

inline

Copy constructor.

Constructs a new tiled_extent from the supplied argument "other".

Parameters

[in] other An object of type tiled_extent from which to initialize this new extent.

template<int D0, int D1>

Concurrency::tiled_extent< D0, D1, 0 >::tiled_extent ( const extent< 2 > & ext )

inline

Constructs a tiled_extent<N> with the extent "ext".

Notice that this constructor allows implicit conversions from extent<N> to tiled_extent<N>.

Parameters

[in] ext The extent of this tiled_extent

Member Function Documentation

template<int D0, int D1>

extent<2> Concurrency::tiled_extent< D0, D1, 0 >::get_tile_extent ( ) const

Returns an instance of an extent<N> that captures the values of the tiled_extent template arguments D0, D1, and D2.

For example:

tiled_extent<64,16,4> tg;
extent<3> myTileExtent = tg.tile_extent;
assert(myTileExtent[0] == 64);
assert(myTileExtent[1] == 16);
assert(myTileExtent[2] == 4);

template<int D0, int D1>

tiled_extent& Concurrency::tiled_extent< D0, D1, 0 >::operator= ( const tiled_extent< D0, D1, 0 > & other )

Assigns the component values of "other" to this tiled_extent<N> object.

Parameters

[in] other An object of type tiled_extent<N> from which to copy into this.

Returns: Returns *this.

template<int D0, int D1>

tiled_extent Concurrency::tiled_extent< D0, D1, 0 >::pad ( ) const

inline

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

The origin of the new tiled_extent is the same as the origin of this one.

template<int D0, int D1>

tiled_extent Concurrency::tiled_extent< D0, D1, 0 >::truncate ( ) const

inline

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

The origin of the new tiled_extent is the same as the origin of this one.

	)

friend

Compares two objects of tiled_extent<N>.

The expression lhs $\oplus$ rhs is true if lhs.extent $\oplus$ rhs.extent and lhs.origin $\oplus$ rhs.origin.
