Detailed Description

Internal classes used for the implementation of multidimensional arrays.

Function Documentation

template<typename MAPT >

bool pni::core::is_contiguous	(	const MAPT &	map,
		const array_selection &	s
	)

This function returns true if a selection is continuous within a index map. A selection is considered as contiguous if the number of it spans in the original array is equal to the size of the selection.

Template Parameters

MAPT	index map type

Parameters

map	reference to the index mape
s	reerence to the selection.

Returns

true if contiguous, false otherwise

template<typename MAPT >

size_t pni::core::last_offset	(	const MAPT &	map,
		const array_selection &	s
	)

Compute the linear offset in the original array for the last element in a selection.

Template Parameters

MAPT	index map type of the original array
INDEXT	index type of the array selection

Parameters

map	reference to the original index map
s	reference to the selection object

Returns

offset of the last element

template<typename MAPT , typename CTYPE >

size_t pni::core::offset	(	const MAPT &	map,
		const array_selection &	s,
		const CTYPE &	index
	)

Compute the offset of a selection element in the original array. The original array is not required but only its index map. The index is expected to have the effective size of the selection. This means that its rank can be smaller than that of the map.

Template Parameters

MAPT	map type of the original array
CTYPE	index type for the selection index

Parameters

map	reference to the original index map
s	reference to the selection object
index	reference to the selection index

Returns

linear offset of the element in the original array

template<typename ITERABLE >

scalar_iterator<ITERABLE> pni::core::operator+	(	const scalar_iterator< ITERABLE > &	a,
		ssize_t	b
	)

Add an offset to the iterator and thus increment its internal state by this offset.

Iteartor<...> iter = ...'
Iteartor<...> iter2 = iter+2;

!

Parameters

a	original iterator
b	offset to add

Returns

new iterator

template<typename ITERABLE >

scalar_iterator<ITERABLE> pni::core::operator+	(	ssize_t	a,
		const scalar_iterator< ITERABLE > &	b
	)

Add an offset to the iterator and thus increment its internal state by this offset.

Parameters

a	offset to add
b	original iterator

Returns

new iterator

template<typename ITERABLE >

scalar_iterator<ITERABLE> pni::core::operator-	(	const scalar_iterator< ITERABLE > &	a,
		ssize_t	b
	)

Subtract an integer offset from the iterator and thus decrement the internal state of the iterator by this value.

Parameters

a	original iterator
b	offset

Returns

new iterator to new position

template<typename ITERABLE >

ssize_t pni::core::operator-	(	const scalar_iterator< ITERABLE > &	a,
		const scalar_iterator< ITERABLE > &	b
	)

Subtract to iterators and return the offset difference between this two iterators.

Parameters

a	first iterator
b	second iterator

Returns

offset difference

template<typename MAPT >

size_t pni::core::start_offset	(	const MAPT &	map,
		const array_selection &	s
	)

Compute the offset in the original array of the first element in the selection.

Template Parameters

MAPT	original index map type
INDEXT	index type of the selection

Parameters

map	reference to the original index map
s	reference to the selection

Returns

offset of the first selection element
