Function Documentation

CompareItems()

template<typename ElementType , typename SizeType >

FORCEINLINE bool CompareItems	(	const ElementType *	A,
		const ElementType *	B,
		SizeType	Count )

Definition at line 244 of file MemoryOps.h.

ConstructItems()

template<typename DestinationElementType , typename SourceElementType , typename SizeType >

FORCEINLINE void ConstructItems	(	void *	Dest,
		const SourceElementType *	Source,
		SizeType	Count )

Constructs a range of items into memory from a set of arguments. The arguments come from an another array.

Parameters

Dest	The memory location to start copying into.
Source	A pointer to the first argument to pass to the constructor.
Count	The number of elements to copy.

Definition at line 109 of file MemoryOps.h.

CopyAssignItems()

template<typename ElementType , typename SizeType >

FORCEINLINE void CopyAssignItems	(	ElementType *	Dest,
		const ElementType *	Source,
		SizeType	Count )

Copy assigns a range of items.

Parameters

Dest	The memory location to start assigning to.
Source	A pointer to the first item to assign.
Count	The number of elements to assign.

Definition at line 135 of file MemoryOps.h.

DefaultConstructItems()

template<typename ElementType , typename SizeType >

FORCEINLINE void DefaultConstructItems	(	void *	Address,
		SizeType	Count )

Default constructs a range of items in memory.

Parameters

Elements	The address of the first memory location to construct at.
Count	The number of elements to destruct.

Definition at line 39 of file MemoryOps.h.

DestructItem()

template<typename ElementType >

FORCEINLINE void DestructItem

(

ElementType *

Element

)

Destructs a single item in memory.

Parameters

Elements

A pointer to the item to destruct.

Note

: This function is optimized for values of T, and so will not dynamically dispatch destructor calls if T's destructor is virtual.

Definition at line 65 of file MemoryOps.h.

DestructItems()

template<typename ElementType , typename SizeType >

FORCEINLINE void DestructItems	(	ElementType *	Element,
		SizeType	Count )

Destructs a range of items in memory.

Parameters

Elements	A pointer to the first item to destruct.
Count	The number of elements to destruct.

Note

: This function is optimized for values of T, and so will not dynamically dispatch destructor calls if T's destructor is virtual.

Definition at line 85 of file MemoryOps.h.

MoveAssignItems()

template<typename ElementType , typename SizeType >

FORCEINLINE void MoveAssignItems	(	ElementType *	Dest,
		const ElementType *	Source,
		SizeType	Count )

Move assigns a range of items.

Parameters

Dest	The memory location to start move assigning to.
Source	A pointer to the first item to move assign.
Count	The number of elements to move assign.

Definition at line 225 of file MemoryOps.h.

MoveConstructItems()

template<typename ElementType , typename SizeType >

FORCEINLINE void MoveConstructItems	(	void *	Dest,
		const ElementType *	Source,
		SizeType	Count )

Move constructs a range of items into memory.

Parameters

Dest	The memory location to start moving into.
Source	A pointer to the first item to move from.
Count	The number of elements to move.

Definition at line 199 of file MemoryOps.h.

RelocateConstructItems()

template<typename DestinationElementType , typename SourceElementType , typename SizeType >

FORCEINLINE void RelocateConstructItems	(	void *	Dest,
		const SourceElementType *	Source,
		SizeType	Count )

Relocates a range of items to a new memory location as a new type. This is a so-called 'destructive move' for which there is no single operation in C++ but which can be implemented very efficiently in general.

Parameters

Dest	The memory location to relocate to.
Source	A pointer to the first item to relocate.
Count	The number of elements to relocate.
