Provides an index into a tiled_extent object. This class has properties to access elements relative to the local tile origin and relative to the global origin. For more information about tiled spaces, see Using Tiles.

Syntax

template <
    int _Dim0,  
    int _Dim1 = 0,  
    int _Dim2 = 0  
>  
class tiled_index : public _Tiled_index_base<3>;  
 
template <
    int _Dim0,  
    int _Dim1  
>  
class tiled_index<_Dim0, _Dim1, 0> : public _Tiled_index_base<2>;  
 
template <
    int _Dim0  
>  
class tiled_index<_Dim0, 0, 0> : public _Tiled_index_base<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.
