Functions

Type	Name	Description
ElementType *	begin ()	DO NOT USE DIRECTLY STL-like iterators to enable range-based for loop support.
void	CheckInvariants ()	Checks array invariants: if array size is greater than zero on each dimension
bool	Contains ( const ComparisonType& Item )	Checks if this array contains the element.
void	DimensionCheck ( uint8 Dimension )	Checks if a dimension is within the allowed number of dimensions
ElementType *	end ()
const PointerType	GetData ()	Helper function for returning a typed pointer to the first array entry.
PointerType	GetData ()	Helper function for returning a typed pointer to the first array entry.
constexpr size_t	GetTypeAlignment ()	Helper function returning the alignment of the inner type.
constexpr size_t	GetTypeSize ()	Helper function returning the size of the inner type.
bool	IsEmpty ()	Returns true if the array is empty and contains no elements.
bool	IsEmpty ( uint8 Dimension )	Returns true if the dimension is empty and contains no elements.
SizeType	Num ()	Returns the total number of elements
SizeType	Num ()	Returns the number of elements in a dimension.
SizeType	Num ( uint8 Dimension )	Returns the number of elements in a dimension.
void	RangeCheck ( uint8 Dimension, SizeType Index )	Checks if index is in dimension range.
SizeType	Rank ()	Returns the number of dimensions.
TMultiArrayShape< DimNum, SizeType >	Shape ()	Returns the number of elements in each dimension.
TMultiArrayView	Slice ( SizeType Index, SizeType InNum )	Returns a sliced view. Slicing outside of the range of the view is illegal.
void	SliceRangeCheck ( uint8 Dimension, SizeType Index, SizeType InNum )	Checks if a slice range [Index, Index+InNum) is in dimension range.
SizeType	Stride ( uint8 Dimension )	Returns the stride for a dimension.
	TMultiArrayView ( ElementType* InData, TMultiArrayShape< DimNum, SizeType > InShape )	Construct a view of an arbitrary pointer
	TMultiArrayView ()	Constructor.
	TMultiArrayView ( OtherRangeType&& Other )	Constructor from another range
	TMultiArrayView ( std::initializer_list< ElementType > List )	Construct a view of an initializer list.
	TMultiArrayView ( OtherElementType* InData, SizeType InNum )	Construct a view of an arbitrary pointer

Operators

Type	Name	Description
	operator TArrayView< ElementType, SizeType > ()	Implicit cast to TArrayView.
	operator TMultiArrayView< DimNum, const ElementType, false, false, SizeType > ()	Implicit cast for Checked and Restrict.
	operator TMultiArrayView< DimNum, const ElementType, false, true, SizeType > ()	Implicit cast for Checked and Restrict.
	operator TMultiArrayView< DimNum, const ElementType, true, false, SizeType > ()	Implicit cast for Checked and Restrict.
	operator TMultiArrayView< DimNum, const ElementType, true, true, SizeType > ()	Implicit cast for Checked and Restrict.
	operator TMultiArrayView< DimNum, ElementType, false, false, SizeType > ()	Implicit cast for Checked and Restrict.
	operator TMultiArrayView< DimNum, ElementType, false, true, SizeType > ()	Implicit cast for Checked and Restrict.
	operator TMultiArrayView< DimNum, ElementType, true, false, SizeType > ()	Implicit cast for Checked and Restrict.
	operator TMultiArrayView< DimNum, ElementType, true, true, SizeType > ()	Implicit cast for Checked and Restrict.
ElementType &	operator[] ( SizeType Index )	Array bracket operator. Returns a reference to the element at given index.
