class TChunkedArray

An array that uses multiple allocations to avoid allocation failure due to fragmentation.

	Type	Name	Description
	ChunksType	Chunks
	int32	NumElements	The number of elements in the array.

	Type	Name	Description
		TChunkedArray ( int32 InNumElements )	Initialization constructor.
		TChunkedArray ( TChunkedArray&& Other )
		TChunkedArray ( const TChunkedArray& )

Type	Name	Description
int32	Add ( int32 Count )
int32	AddElement ( const ElementType& Item )	Adds a new item to the end of the chunked array.
FConstIterType	begin ()
FIterType	begin ()
void	CopyToLinearArray ( TArray< ElementType, OtherAllocator >& DestinationArray )
void	Empty ( int32 Slack )
FConstIterType	end ()
FIterType	end ()
SIZE_T	GetAllocatedSize ()
bool	IsEmpty ()	Returns true if the chunked array is empty and contains no elements.
bool	IsValidIndex ( int32 Index )	Tests if index is valid, i.e. greater than zero and less than number of elements in array.
int32	Num ()
void	Reserve ( int32 Number )	Reserves memory such that the array can contain at least Number elements.
void	Shrink ()

Type	Name	Description
ElementType &	operator() ( int32 ElementIndex )	Accessors.
const ElementType &	operator() ( int32 ElementIndex )
ElementType &	operator[] ( int32 ElementIndex )
const ElementType &	operator[] ( int32 ElementIndex )
TChunkedArray &	operator+= ( const TArray< ElementType >& Other )	Appends the specified array to this array. Cannot append to self.
