Name	FRawStaticIndexBuffer16or32Interface
Type	class
Header File	/Engine/Source/Runtime/Engine/Public/RawIndexBuffer.h
Include Path	#include "RawIndexBuffer.h"

Syntax

class FRawStaticIndexBuffer16or32Interface : public FIndexBuffer

Name	Remarks	Include Path
int32 AddItem ( uint32 Val )		RawIndexBuffer.h
void Empty ( int32 Slack )		RawIndexBuffer.h
uint32 Get ( uint32 Idx ) const		RawIndexBuffer.h
bool GetNeedsCPUAccess()	The following methods are basically just accessors that allow us to hide the implementation of FRawStaticIndexBuffer16or32 by making the index array a private member	RawIndexBuffer.h
FShaderResourceViewRHIRef GetOrCreateSRV ( FRHICommandListBase& RHICmdList ) const	Allows for creating SRV on demand Note: consider cache the SRV locally if multiple compute tasks all need access to one in a single frame	RawIndexBuffer.h
void * GetPointerTo ( uint32 Idx )		RawIndexBuffer.h
int32 GetResourceDataSize()		RawIndexBuffer.h
FRHIShaderResourceView * GetSRV()		RawIndexBuffer.h
void Insert ( int32 Idx, int32 Num )		RawIndexBuffer.h
int32 Num()	Number of indices (e.g. 4 triangles would result in 12 elements)	RawIndexBuffer.h
void Remove ( int32 Idx, int32 Num )		RawIndexBuffer.h
void Serialize ( FArchive& Ar )		RawIndexBuffer.h
void SerializeMetaData ( FArchive& Ar )		RawIndexBuffer.h
void SetMetaData ( int32 InCachedNumIndices )		RawIndexBuffer.h

Name	Remarks	Include Path
void InitRHIForStreaming ( FRHIBuffer* IntermediateBuffer, size_t IndexSize, FRHIResourceReplaceBatcher& Batcher )	Similar to Init/ReleaseRHI but only update existing SRV so references to the SRV stays valid	RawIndexBuffer.h
bool IsShaderResource ( bool bAllowCPUAccess ) const		RawIndexBuffer.h
bool IsSRVCreatedByDefault ( bool bAllowCPUAccess ) const		RawIndexBuffer.h
bool IsSRVNeeded ( bool bAllowCPUAccess ) const		RawIndexBuffer.h
void ReleaseRHIForStreaming ( FRHIResourceReplaceBatcher& Batcher )		RawIndexBuffer.h
