Syntax

class FRawStaticIndexBuffer16or32Interface : public FIndexBuffer

Remarks

Virtual interface for the FRawStaticIndexBuffer16or32 class

Variables

  Type Name Description
Protected variable FShaderResourceViewRHIRef SRVValue Guaranteed only to be valid if the vertex buffer is valid and the buffer was created with the SRV flags

Functions

  Type Name Description
Public function int32

AddItem ( uint32 Val
)

  
Protected function Static FBufferRHIRef

CreateRHIIndexBufferInternal ( FRHICommandListBase& RHICmdList,
const TCHAR* InDebugName,
const FName& InOwnerName,
int32 IndexCount,
size_t IndexSize,
FResourceArrayInterface* ResourceArray,
bool bNeedSRV
)

  
Public function void

Empty ( int32 Slack
)

  
Public function Const uint32

Get ( uint32 Idx
)

  
Public function Const bool The following methods are basically just accessors that allow us to hide the implementation of FRawStaticIndexBuffer16or32 by making the index array a private member
Public function void *  
Public function Const int32  
Public function Const FRHIShaderResourceView *

GetSRV ()

  
Protected function void

InitRHIForStreaming ( FRHIBuffer* IntermediateBuffer,
size_t IndexSize,
FRHIResourceUpdateBatcher& Batcher
)

 Similar to Init/ReleaseRHI but only update existing SRV so references to the SRV stays valid
Public function void

Insert ( int32 Idx,
int32 Num
)

  
Protected function Const bool

IsSRVNeeded ( bool bAllowCPUAccess
)

  
Public function Const int32

Num ()

 Number of indices (e.g. 4 triangles would result in 12 elements)
Protected function void  
Public function void

Remove ( int32 Idx,
int32 Num
)

  
Public function void  
Public function void
