Member Function Documentation

UnloadData()

xiiResourceLoadDescription xiiTexture2DResource::UnloadData ( Unload WhatToUnload )

overrideprotectedvirtual

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 xiiTexture2DResource::UpdateContent ( xiiStreamReader * pStream )

overrideprotectedvirtual

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 xiiTexture2DResource::UpdateMemoryUsage ( MemoryUsage & out_NewMemoryUsage )

overrideprotectedvirtual

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.
