Member Function Documentation

Add()

virtual EAddComponentResult IRenderAssetInstanceManager::Add ( const UPrimitiveComponent *  Component, FStreamingTextureLevelContext &  LevelContext, float  MaxAllowedUIDensity  )

pure virtual

Add a component streaming data, the LevelContext gives support for precompiled data.

Implemented in FStaticRenderAssetInstanceManager, and FDynamicRenderAssetInstanceManager.

CanManage()

virtual bool IRenderAssetInstanceManager::CanManage ( const UPrimitiveComponent *  Component ) const

pure virtual

Return whether this component is be managed by this manager.

Implemented in FDynamicRenderAssetInstanceManager, and FStaticRenderAssetInstanceManager.

GetAllocatedSize()

virtual uint32 IRenderAssetInstanceManager::GetAllocatedSize ( ) const

pure virtual

Return the size taken for sub-allocation.

Implemented in FDynamicRenderAssetInstanceManager, and FStaticRenderAssetInstanceManager.

GetAsyncView()

virtual const FRenderAssetInstanceView * IRenderAssetInstanceManager::GetAsyncView ( bool  bCreateIfNull )

pure virtual

Return a view of the data that has to be 100% thread safe. The content is allowed to be updated, but not memory must be reallocated.

Implemented in FDynamicRenderAssetInstanceManager, and FStaticRenderAssetInstanceManager.

IsReferenced()

virtual bool IRenderAssetInstanceManager::IsReferenced ( const UPrimitiveComponent *  Component ) const

pure virtual

Return whether the component is referenced.

Implemented in FDynamicRenderAssetInstanceManager, and FStaticRenderAssetInstanceManager.

PrepareAsyncView()

virtual void IRenderAssetInstanceManager::PrepareAsyncView ( )

pure virtual

Notify the manager that an async view will be requested on the next frame.

Implemented in FDynamicRenderAssetInstanceManager, and FStaticRenderAssetInstanceManager.

Refresh()

virtual void IRenderAssetInstanceManager::Refresh ( float  Percentage )

pure virtual

Refresh component data (bounds, last render time, min and max view distance) - see TextureInstanceView.

Implemented in FDynamicRenderAssetInstanceManager, and FStaticRenderAssetInstanceManager.

Remove()

virtual void IRenderAssetInstanceManager::Remove ( const UPrimitiveComponent *  Component, FRemovedRenderAssetArray *  RemovedTextures  )

pure virtual

Remove a component, the RemoveTextures is the list of textures not referred anymore.

Implemented in FDynamicRenderAssetInstanceManager, and FStaticRenderAssetInstanceManager.
