@InterfaceAudience.Private
public interface PropagatingConfigurationObserver
extends ConfigurationObserver

This extension to ConfigurationObserver allows the configuration to propagate to the children of the current ConfigurationObserver. This is the preferred way to make a class online configurable because it allows the user to configure the children in a recursive manner automatically.
