Syntax

class FRenderResource

Remarks

A rendering resource which is owned by the rendering thread.

Adding new virtual methods to this class may require stubs added to FViewport/FDummyViewport, otherwise certain modules may have link errors

Constructors

	Name	Description
	FRenderResource()	Default constructor.
	FRenderResource ( ERHIFeatureLevel::Type InFeatureLev... )	Constructor when we know what feature level this resource should support

Destructors

	Name	Description
	~FRenderResource()	Destructor used to catch unreleased resources.

Functions

	Name	Description
void	ChangeFeatureLevel ( ERHIFeatureLevel::Type NewFeatureLe... )
void	ForAllResources ( const FunctionType& Function )
void	ForAllResourcesReverse ( const FunctionType& Function )
const FStati...	GetFeatureLevel()
FString	GetFriendlyName()
bool	HasValidFeatureLevel()
void	InitDynamicRHI()	Initializes the dynamic RHI resource and/or RHI render target used by this resource.
void	InitPreRHIResources()	Initialize all resources initialized before the RHI was initialized
void	InitResource()	Initializes the resource. This is only called by the rendering thread.
void	InitRHI()	Initializes the RHI resources used by this resource.
void	InitRHIForAllResources()
bool	IsInitialized()	Accessors.
void	ReleaseDynamicRHI()	Releases the dynamic RHI resource and/or RHI render target resources used by this resource.
void	ReleaseResource()	Prepares the resource for deletion. This is only called by the rendering thread.
void	ReleaseRHI()	Releases the RHI resources used by this resource.
void	ReleaseRHIForAllResources()
void	SetFeatureLevel ( const FStaticFeatureLevel InFeature... )	This is used during mobile editor preview refactor, this will eventually be replaced with a parameter to InitRHI() etc..
void	UpdateRHI()	If the resource's RHI resources have been initialized, then release and reinitialize it.
