Method Detail

buildLoadData

public ModelLoader.LoadData<Data> buildLoadData(Uri model,
                                                int width,
                                                int height,
                                                Options options)

Description copied from interface: ModelLoader

Returns a ModelLoader.LoadData containing a DataFetcher required to decode the resource represented by this model, as well as a set of Keys that identify the data loaded by the DataFetcher as well as an optional list of alternate keys from which equivalent data can be loaded. 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.

Specified by:

buildLoadData in interface ModelLoader<Uri,Data>

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.

handles

public boolean handles(Uri model)

Description copied from interface: ModelLoader

Returns true if the given model is a of a recognized type that this loader can probably load.

For example, you may want multiple Uri -> InputStream loaders. One might handle media store Uris, another might handle asset Uris, and a third might handle file Uris etc.

This method is generally expected to do no I/O and complete quickly, so best effort results are acceptable. ModelLoaders that return true from this method may return null from ModelLoader.buildLoadData(Object, int, int, Options)

Specified by:

handles in interface ModelLoader<Uri,Data>
