IsResourceOutdated()

bool ezTextureResourceLoader::IsResourceOutdated ( const ezResource *  pResource ) const

overridevirtual

If this function returns true, a resource is unloaded and loaded again to update its content.

Call ezResource::GetLoadedFileModificationTime() to query the file modification time that was returned through ezResourceLoadData::m_LoadedFileModificationDate.

Reimplemented from ezResourceTypeLoader.

OpenDataStream()

ezResourceLoadData ezTextureResourceLoader::OpenDataStream ( const ezResource *  pResource )

overridevirtual

Override this function to implement the resource loading.

This function should take the information from pResource, e.g. which file to load, and do the loading work. It should allocate temporary storage for the loaded data and encode it in a memory stream, such that the resource can read all necessary information from the stream.
