Detailed Description

template<typename T>
class sydevs::arraynd< T, 1 >

A one-dimensional (1D) specialization of the arraynd multidimensional array template.

Constructor & Destructor Documentation

template<typename T >

sydevs::arraynd< T, 1 >::arraynd ( )

Constructs a 1D arraynd object of length zero.

template<typename T >

sydevs::arraynd< T, 1 >::arraynd	(	const std::array< int64, 1 > &	dims,
		const T &	value
	)

Constructs a 1D arraynd object with the length specified in dims[0] and all elements initialized to value.

template<typename T >

sydevs::arraynd< T, 1 >::arraynd	(	const std::array< int64, 1 > &	dims,
		const std::vector< T > &	data
	)

Constructs a 1D arraynd object with the length specified in dims[0] and elements initialized with the supplied data.

The supplied data vector must have a length equal to dims[0] so that the 1D multidimensional array can be filled. Otherwise, a std::domain_error exception is thrown. The elements ofdata` are copied into the multidimensional array in row-major order.

Parameters

dims	The dimensions.
data	A vector of values to be copied into the multidimensional array.

template<typename T >

sydevs::arraynd< T, 1 >::arraynd	(	const std::array< int64, 1 > &	dims,
		std::function< T(const std::array< int64, 1 > &indices)>	func
	)

Constructs a 1D arraynd object with the length specified in dims[0] and elements initialized using the function object func.

The function object func maps a set of indices to the value that will be assigned to the corresponding location in the 1D multidimensional array.

Parameters

dims	The dimensions.
func	The function object invoked to initialize each element.
