Method Detail

getResourceFetcher

public final DataFetcher<T> getResourceFetcher(Uri 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<Uri,T>

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.
