FRDGBufferRef CreateByteAddressUploadBuffer ( FRDGBuilder& GraphBuilder,
const TCHAR* Name,
GetArrayRefCallback&& ArrayCallback
)

 Same as the previous function but where the type of the array is automatically inferred, so we can do : TArray Array = GraphBuilder.AllocArray<...>(); CreateByteAddressBuffer(..., & -> auto&{ return Array; }); RenderGraphUtils.h  

FRDGBufferRef CreateByteAddressUploadBuffer ( FRDGBuilder& GraphBuilder,
const TCHAR* Name,
const TArray< ElementType, AllocatorType >& InitialData,
ERDGInitialDataFlags InitialDataFlags
)

 Helper to create a byte address upload buffer with initial data from a TArray. RenderGraphUtils.h  

FRDGBufferRef CreateByteAddressUploadBuffer ( FRDGBuilder& GraphBuilder,
const TCHAR* Name,
FRDGBufferNumElementsCallback&& NumElementsCallback,
FRDGBufferInitialDataCallback&& InitialDataCallback,
FRDGBufferInitialDataSizeCallback&& InitialDataSizeCallback
)

 A variant where NumElements, InitialData, and InitialDataSize are supplied through callbacks. RenderGraphUtils.h  

CreateByteAddressUploadBuffer(FRDGBuilder &, const TCHAR *, GetArrayRefCallback &&)

Description

Same as the previous function but where the type of the array is automatically inferred, so we can do : TArray Array = GraphBuilder.AllocArray<...>(); CreateByteAddressBuffer(..., & -> auto&{ return Array; });

CreateByteAddressUploadBuffer(FRDGBuilder &, const TCHAR *, const TArray< ElementType, AllocatorType > &, ERDGInitialDataFlags)

Description

Helper to create a byte address upload buffer with initial data from a TArray. NOTE: does not provide a 1-size fallback for empty initial data.

CreateByteAddressUploadBuffer(FRDGBuilder &, const TCHAR *, FRDGBufferNumElementsCallback &&, FRDGBufferInitialDataCallback &&, FRDGBufferInitialDataSizeCallback &&)

Description

A variant where NumElements, InitialData, and InitialDataSize are supplied through callbacks. This allows creating a buffer with information unknown at creation time. Though, data must be ready before the most recent RDG pass that references the buffer is executed. For byte address buffers, NumElements must be Size / 4.
