class FUniqueBuffer

A reference to a single-ownership mutable buffer.

Ownership can be transferred by moving to FUniqueBuffer or it can be converted to an immutable shared buffer with MoveToShared().

	Type	Name	Description
		FUniqueBuffer ()	Construct a null unique buffer.
		FUniqueBuffer ( FBufferOwner* Owner )	Construct a unique buffer from a new unreferenced buffer owner.
		FUniqueBuffer ( FUniqueBuffer&& )
		FUniqueBuffer ( const FUniqueBuffer& )

Type	Name	Description
FUniqueBuffer	Alloc ( uint64 Size )	Make an uninitialized owned buffer of the specified size.
FUniqueBuffer	AllocZeroed ( uint64 Size )	Make a zeroed owned buffer of the specified size.
FUniqueBuffer	Clone ( const void* Data, uint64 Size )
FUniqueBuffer	Clone ( FMemoryView View )	Make an owned clone of the input.
const void *	GetData ()
void *	GetData ()	Returns a pointer to the start of the buffer.
uint64	GetSize ()	Returns the size of the buffer in bytes.
FMemoryView	GetView ()
FMutableMemoryView	GetView ()	Returns a view of the buffer.
bool	IsMaterialized ()	Returns true if the referenced buffer has been materialized.
bool	IsNull ()	Returns true if this does not point to a buffer owner.
bool	IsOwned ()	Returns true if this keeps the referenced buffer alive.
FUniqueBuffer	MakeOwned ()	Returns a buffer that is owned, by cloning if not owned.
FUniqueBuffer	MakeView ( FMutableMemoryView View )	Make a non-owned view of the input.
FUniqueBuffer	MakeView ( void* Data, uint64 Size )
void	Materialize ()	Materialize the buffer by making its data and size available.
FSharedBuffer	MoveToShared ()	Convert this to an immutable shared buffer, leaving this null.
void	Reset ()	Reset this to null.
FUniqueBuffer	TakeOwnership ( void* Data, uint64 Size, DeleteFunctionType&& DeleteFunction )	Make an owned buffer by taking ownership of the input.
FUniqueBuffer	TakeOwnership ( void* Data, uint64 Size, DeleteFunctionType&& DeleteFunction )	Make an owned buffer by taking ownership of the input.

Type	Name	Description
	operator bool ()	Returns true if this points to a buffer owner.
	operator FMemoryView ()
	operator FMutableMemoryView ()
bool	operator!= ( const FUniqueBuffer& BufferB )
FUniqueBuffer &	operator= ( FUniqueBuffer&& )
FUniqueBuffer &	operator= ( const FUniqueBuffer& )
bool	operator== ( const FUniqueBuffer& BufferB )
