Class CountDownActionListener

java.lang.Object

org.elasticsearch.action.DelegatingActionListener<Void,Void>

org.elasticsearch.action.support.CountDownActionListener

All Implemented Interfaces:

ActionListener<Void>

public final class CountDownActionListener
extends DelegatingActionListener<Void,Void>

Wraps another listener and adds a counter -- each invocation of this listener will decrement the counter, and when the counter has been exhausted the final invocation of this listener will delegate to the wrapped listener. Similar to GroupedActionListener, but for the cases where tracking individual results is not useful.
