We should clarify that in the documentation by adding a comment such as:
Code:
public interface MessageGroupStore {
void registerMessageGroupExpiryCallback(MessageGroupCallback callback);
int expireMessageGroups(long timeout);
// other methods omitted
}
The reason only those two are shown in that particular section of the reference manual is that they are the only 2 methods relevant to the 'callback' discussion.
Could you please open an issue in JIRA so that we can address this for an upcoming release?
Thanks,
Mark
