Detailed Description

template<typename T, int64 ndims>
class sydevs::arraynd_base< T, ndims >

A base class template for a multidimensional array with elements of type T arranged in a lattice of ndim dimensions.

arraynd_base contains all member variables, all member functions that behave the same for ndims == 1 and ndims > 1, and all member functions that do not return a multidimensional array.

bool sydevs::arraynd_base< T, ndims >::traverse ( std::function< bool(const std::array< int64, ndims > &indices, const T &value)> func ) const

Traverses the multidimensional array in row-major order, calling func at every element.

For each element traversed in row-major order, func is called with the indices of the element and the element's value. If func returns true, the traversal continues. If func returns false, the traversal is terminated.

Parameters

func	The function to be called at every element.

Returns: true if the entire multidimensional array is traversed and func returns true at every element; false otherwise.
