Functions

Public

Name Remarks Include Path Unreal Specifiers

void CreateUntrackedElement ( const FPooledRenderTargetDesc& Desc,
TRefCountPtr< IPooledRenderTarget >& Out,
const FSceneRenderTargetItem& Item
)

   RenderTargetPool.h  

void DumpMemoryUsage ( FOutputDevice& OutputDevice
)

 Logs out usage information. RenderTargetPool.h  

bool FindFreeElement ( FRHICommandListBase& RHICmdList,
const FPooledRenderTargetDesc& Desc,
TRefCountPtr< IPooledRenderTarget >& Out,
const TCHAR* InDebugName
)

   RenderTargetPool.h  

bool FindFreeElement ( FRHICommandListBase& RHICmdList,
const FRHITextureCreateInfo& Desc,
TRefCountPtr< IPooledRenderTarget >& Out,
const TCHAR* Name
)

   RenderTargetPool.h  

bool FindFreeElement ( const FRHITextureCreateInfo& Desc,
TRefCountPtr< IPooledRenderTarget >& Out,
const TCHAR* Name
)

   RenderTargetPool.h  

TRefCountPtr< IPooledRenderTarget > FindFreeElement ( FRHICommandListBase& RHICmdList,
FRHITextureCreateInfo Desc,
const TCHAR* Name
)

   RenderTargetPool.h  

TRefCountPtr< IPooledRenderTarget > FindFreeElement ( FRHITextureCreateInfo Desc,
const TCHAR* Name
)

   RenderTargetPool.h  

int32 FindIndex ( IPooledRenderTarget* In
) const

   RenderTargetPool.h  

void FreeUnusedResource ( TRefCountPtr< IPooledRenderTarget >& In
)

 Allows to remove a resource so it cannot be shared and gets released immediately instead a/some frame[s] later. RenderTargetPool.h  

void FreeUnusedResources()

 Good to call between levels or before memory intense operations. RenderTargetPool.h  

FPooledRenderTarget * GetElementById ( uint32 Id
) const

 For debugging purpose, assumes you call FlushRenderingCommands() be RenderTargetPool.h  

uint32 GetElementCount()

   RenderTargetPool.h  

void GetStats ( uint32& OutWholeCount,
uint32& OutWholePoolInKB,
uint32& OutUsedInKB
) const

 Only to get statistics on usage and free elements. RenderTargetPool.h  

void TickPoolElements()

 Can release RT, should be called once per frame. call from RenderThread only RenderTargetPool.h  

Overridden from FRenderResource

Name Remarks Include Path Unreal Specifiers

virtual void ReleaseRHI()

 Free renderer resources RenderTargetPool.h
