ModelLoader
DataFetcher
that can fetch the data required to decode the resource represented by this model.
The DataFetcher
will not be used if the resource is already cached.
Note - If no valid data fetcher can be returned (for example if a model has a null URL), then it is acceptable to return a null data fetcher from this method. Doing so will be treated any other failure or exception during the load process.
