Class IgnoreExtraResponsesValidityFilter

java.lang.Object

org.infinispan.remoting.responses.IgnoreExtraResponsesValidityFilter

All Implemented Interfaces:

ResponseFilter

public final class IgnoreExtraResponsesValidityFilter
extends Object
implements ResponseFilter

A filter that only expects responses from an initial set of targets. Useful when sending a command to null to ensure we don't wait for responses from cluster members that weren't properly started when the command was sent. JGroups calls our handler while holding a lock, so we don't need any synchronization.

Since:

5.1
