org.elasticsearch.action.support.GroupedActionListener<T>

All Implemented Interfaces:

ActionListener<T>

public final class GroupedActionListener<T>
extends <T>>

An action listener that delegates its results to another listener once it has received N results (either successes or failures). This allows synchronous tasks to be forked off in a loop with the same listener and respond to a higher level listener once all tasks responded.
