getResourceFetcher
public DataFetcher<InputStream> getResourceFetcher(T model,
int width,
int height)
- Description copied from interface:
ModelLoader
- Obtains an
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.
- Specified by:
getResourceFetcher
in interface ModelLoader<T,InputStream>
- Parameters:
model
- The model representing the resource.width
- The width in pixels of the view or target the resource will be loaded into, or
Target.SIZE_ORIGINAL
to indicate that the resource should
be loaded at its original width.height
- The height in pixels of the view or target the resource will be loaded into, or
Target.SIZE_ORIGINAL
to indicate that the resource should
be loaded at its original height.
- Returns:
- A
DataFetcher
that can obtain the data the resource can be decoded from if the resource is not
cached, or null if no valid DataFetcher
could be constructed.
