◆ Allocate()

template<typename InValueType , typename InBufferTraits , int32 InNumValuesPerScatter = 1>

static TAsyncBufferScatterUploader * UE::RendererPrivateUtils::Implementation::TAsyncBufferScatterUploader< InValueType, InBufferTraits, InNumValuesPerScatter >::Allocate	(	FRDGBuilder &	GraphBuilder,
		int32	NumScatters = `0`
	)

inlinestatic

Allocate an instance of TAsyncBufferScatterUploader using an allocator tied to the lifetime of the graph

◆ ResizeAndUploadToAsync()

template<typename InValueType , typename InBufferTraits , int32 InNumValuesPerScatter = 1>

FRDGBuffer * UE::RendererPrivateUtils::Implementation::TAsyncBufferScatterUploader< InValueType, InBufferTraits, InNumValuesPerScatter >::ResizeAndUploadToAsync	(	FRDGBuilder &	GraphBuilder,
		TPersistentBuffer< InValueType, InBufferTraits > &	DestDataBuffer,
		int32	DestDataMinimumSize
	)

inline

Resize the destination persistent buffer (if needed) and upload & scatter the collected data to it. Callbacks are used to create upload buffers and scheduling scatter dispatch since data might not be ready yet.
