public class Cached<T> extends Stored<T>
ComponentAdapter
implementation that caches the component instance.This adapter supports components with a lifecycle, as it is a
lifecycle manager
which will apply the delegate'slifecycle strategy
to the cached component instance. The lifecycle state is maintained so that the component instance behaves in the expected way: it can't be started if already started, it can't be started or stopped if disposed, it can't be stopped if not started, it can't be disposed if already disposed.- See Also:
