Public function void

AppendIndices ( const uint32* IndicesToAppend,
const uint32 NumIndicesToAppend
)

 Append indices to the end of the buffer
Public function void  
Public function FBufferRHIRef  
Public function FBufferRHIRef Create an RHI index buffer with CPU data.
Public function void

Discard ()

 Discard discards the serialized data when it is not needed
Public function void Expands the 16bit index buffer to 32bit
Public function Const SIZE_T Computes the amount of memory allocated to store the indices.
Public function Const bool

GetCopy ( TArray< uint32 >& OutIndices
)

 Retrieve a copy of the indices in this buffer.
Public function Const uint32

GetIndex ( const uint32 At
)

  
Public function Const int32 == GetNumIndices() * (b32Bit ? 4 : 2)

const uint32 NumIndicesToRemove
)

 Removes indices from the buffer
Public function void

Serialize ( FArchive& Ar,
bool bNeedsCPUAccess

Public function void

SetIndex ( const uint32 At,
const uint32 NewIndexValue
)

 Sets a single index value.
Public function void

SetIndices ( const TArray< uint32 >& InIndices,
EIndexBufferStride::Type DesiredStride
)

 Set the indices stored within this buffer.
Public function bool

TrySetAllowCPUAccess ( bool bAllowCPUAccess
)

Overridden from FRenderResource

  Type Name Description
Public function Virtual void

InitRHI ( FRHICommandListBase& RHICmdList
)
