Detailed Description

Contains the implementation of LvArray::memcpy.

Function Documentation

slice() [1/2]

template<int N_LEFT, typename T , int NDIM, int USD, typename INDEX_TYPE >

std::enable_if_t< N_LEFT == 0, ArraySlice< T, NDIM, USD, INDEX_TYPE > > LvArray::internal::slice	(	ArraySlice< T, NDIM, USD, INDEX_TYPE > const	curSlice,
		INDEX_TYPE const *
	)

Specialization for when all the indices have been consumed.

Returns

curSlice.

Template Parameters

N_LEFT	The number of indices left to consume, this is a specialization for N_LEFT == 0.
T	The type of values in the slice.
NDIM	The number of dimensions in the slice.
USD	The unit stride dimension of the slice.
INDEX_TYPE	The index type of the slice.

Parameters

curSlice

The slice to return.

slice() [2/2]

template<int N_LEFT, typename T , int NDIM, int USD, typename INDEX_TYPE >

std::enable_if_t< N_LEFT != 0, ArraySlice< T, NDIM - N_LEFT, USD - N_LEFT, INDEX_TYPE > > LvArray::internal::slice	(	ArraySlice< T, NDIM, USD, INDEX_TYPE > const	curSlice,
		INDEX_TYPE const *const	remainingIndices
	)

Slice curSlice until all of remainingIndices have been consumed.

Template Parameters

N_LEFT	The number of indices left to consume.
T	The type of values in the slice.
NDIM	The number of dimensions in the slice.
USD	The unit stride dimension of the slice.
INDEX_TYPE	The index type of the slice.

Parameters

curSlice	The ArraySlice to further slice.
remainingIndices	The indices used to slice curSlice.

Returns

curSlice[ remainingIndices[ 0 ] ][ remainingIndices[ 1 ] ][ ... ]
