public abstract class ForwardingService extends ForwardingObject
    implements Service {

  
Constructor for use by subclasses.
  protected ForwardingService() {}
  @Override protected abstract Service delegate();
  @Override public ListenableFuture<Statestart() {
    return delegate().start();
  }
  @Override public State state() {
    return delegate().state();

    return delegate().stop();
  }
  @Override public State startAndWait() {
    return delegate().startAndWait();

    delegate().addListener(listenerexecutor);
  }

  
A sensible default implementation of startAndWait(), in terms of start(). If you override start(), you may wish to override startAndWait() to forward to this implementation.

Since:
9.0
  protected State standardStartAndWait() {
    return Futures.getUnchecked(start());
  }

  
A sensible default implementation of stopAndWait(), in terms of stop(). If you override stop(), you may wish to override stopAndWait() to forward to this implementation.

Since:
9.0
  protected State standardStopAndWait() {
    return Futures.getUnchecked(stop());
  }
