Detailed Description

An index buffer resource.

Constructor & Destructor Documentation

◆ FIndexBuffer() [1/2]

FIndexBuffer::FIndexBuffer ( )
default

◆ FIndexBuffer() [2/2]

FIndexBuffer::FIndexBuffer ( const FIndexBuffer &  )
default

◆ ~FIndexBuffer()

FIndexBuffer::~FIndexBuffer ( )
virtualdefault

Member Function Documentation

◆ GetFriendlyName()

FString FIndexBuffer::GetFriendlyName ( ) const
overridevirtual
Returns
The resource's friendly name. Typically a UObject name.

Reimplemented from FRenderResource.

◆ GetRHI()

const FBufferRHIRef & FIndexBuffer::GetRHI ( ) const
inline

◆ operator=()

FIndexBuffer & FIndexBuffer::operator= ( const FIndexBuffer &  Other)
default

◆ ReleaseRHI()

void FIndexBuffer::ReleaseRHI ( )
overridevirtual

Releases the RHI resources used by this resource. Called when leaving the state where both the resource and the RHI have been initialized. This is only called by the rendering thread.

Reimplemented from FRenderResource.

Reimplemented in FPooledDynamicMeshIndexBuffer, FRawStaticIndexBuffer16or32< INDEX_TYPE >, and FSortedIndexBuffer.

◆ SetRHI()

void FIndexBuffer::SetRHI ( const FBufferRHIRef &  BufferRHI)
