- ## Method Details

  - ### shutdownImplementationForReload

    boolean shutdownImplementationForReload()
    Invoked when Tapestry notices that the implementation class has changed. The existing instance is notified, so that it can cleanly shutdown now, before being re-instantiated. This is necessary when the service implementation retains some form of external resources. In addition, the implementation may request an immediate reload. Normally, reloading of the service is deferred until a method of the proxy object is invoked (this causes the normal just-in-time instantiation of the implementation). When this method returns true, the implementation is re-created immediately. This is most often the case for services that are eagerly loaded in the first place.
    Returns:
      true if the service should be reloaded immediately, false if reload should be deferred
