Interface ConnectionStateListenerDecorator

  • Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
    @FunctionalInterface
public interface ConnectionStateListenerDecorator

    Allows for the enhancement of the ConnectionStateListener instances used with Curator. Client code that sets a ConnectionStateListener should always wrap it using the configured ConnectionStateListenerDecorator. All Curator recipes do this.

    E.g. 

     CuratorFramework client ...
 ConnectionStateListener listener = ...
 ConnectionStateListener decoratedListener = client.decorateConnectionStateListener(listener);

 ...

 client.getConnectionStateListenable().addListener(decoratedListener);

 // later, to remove...
 client.getConnectionStateListenable().removeListener(decoratedListener);
