Method Details

get

@NonNull
public final T get()

Description copied from interface: Resource

Returns an instance of the wrapped resource.

Note - This does not have to be the same instance of the wrapped resource class and in fact it is often appropriate to return a new instance for each call. For example, Drawables should only be used by a single View at a time so each call to this method for Resources that wrap Drawables should always return a new Drawable.

Specified by:

get in interface Resource<T extends Drawable>

initialize

public void initialize()

Description copied from interface: Initializable

Called on a background thread so the Resource can do some eager initialization.

Specified by:

initialize in interface Initializable
