Member Function Documentation

◆ GetDefaultResourceTypeLoader()

xiiResourceTypeLoader * xiiShaderPermutationResource::GetDefaultResourceTypeLoader ( ) const
overrideprivatevirtual

Returns the resource type loader that should be used for this type of resource, unless it has been overridden on the xiiResourceManager.

By default, this redirects to xiiResourceManager::GetDefaultResourceLoader. So there is one global default loader, that can be set on the resource manager. Overriding this function will then allow to use a different resource loader on a specific type. Additionally, one can override the resource loader from the outside, by setting it via xiiResourceManager::SetResourceTypeLoader. That last method always takes precedence and allows to modify the behavior without modifying the code for the resource. But in the default case, the resource defines which loader is used.

Reimplemented from xiiResource.

◆ UnloadData()

xiiResourceLoadDescription xiiShaderPermutationResource::UnloadData ( Unload WhatToUnload)
overrideprivatevirtual

Requests the resource to unload another quality level. If bFullUnload is true, the resource should unload all data, because it is going to be deleted afterwards.

Implements xiiResource.

◆ UpdateContent()

xiiResourceLoadDescription xiiShaderPermutationResource::UpdateContent ( xiiStreamReader * pStream)
overrideprivatevirtual

Called whenever more data for the resource is available. The resource must read the stream to update it's data.

pStream may be nullptr in case the resource data could not be found.

Implements xiiResource.

◆ UpdateMemoryUsage()

void xiiShaderPermutationResource::UpdateMemoryUsage ( MemoryUsage & out_NewMemoryUsage)
overrideprivatevirtual

This function must be overridden by all resource types.

It has to compute the memory used by this resource. It is called by the resource manager whenever the resource's data has been loaded or unloaded.

Implements xiiResource.
