      • 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.
