bounds_d Template Function

Provides a consistent way to determine the bounds of a dimension for a multi-dimensional object. #include <sdlt/n_extent.h>

Syntax

template<int DimensionT, typename ObjT>
auto bounds_d(const ObjT &a_obj)

Description

Consistent way to determine the bounds of a dimension for a multi-dimensional object. Can avoid extracting an entire n_bounds_t<…> when only the extent of a single dimension is needed.

Template Argument

Description

int DimensionT

0 based index starting at the leftmost dimension indicating which n-dimensions to query the bounds of.

Requirements: DimensionT >=0 and DimensionT < ObjT::rank

typename ObjT

The type of n-dimensional object from which to retrieve the extent.

Requirements: ObtT is one of:

n_container<…>

n_bounds_t<…>

n_bounds_generator<…>

n_container<…>::accessor

n_container<…>::const_accessor

or any sectioned or translated accessor.

Returns:

The correctly typed bounds_t<LowerT, UpperT> corresponding to the requested DimensionT of a_obj.

Example:

template <typename VolumeT>
void foo(const VolumeT & a_volume)
{
    auto bounds_z = bounds_d<0>(volume); 
    auto bounds_y = bounds_d<1>(volume); 
    auto bounds_x = bounds_d<2>(volume); 
    for(auto z : bounds_z)
        for(auto y : bounds_y)
            for(auto x : bounds_x) {
                // …
            }
}
