It's just for PTP messages.
There is no stuff to call to erase PTP / Persistents messages.

If you send a PTP message with a Durable property,
you'll get all the time the message at each server restart...

look at that scenario :

1/ RequestBroker.loadPersistentMessages()
    do a publish() of messages found in persistence folder.

2/ RequestBroker.publish()
    ...
    if (publishQoS.isPubSubStyle()) {
        ...
        messageContainerMap.put();
        ...
    }else if (publishQoS.isPTP_Style()) {
        ...
        destinationClient.sendUpdate();    // <-- Go there
        ...
    }
    ...
}

3/ ClientInfo.sendUpdate()
    ... client not logged ...
    queueMessage(msgUnitWrapper, destination);

4/ ClientInfo.notifyAboutLogin() {
    ...
    if (messageQueue != null) {
        ...
        while (true) {
            MessageUnitWrapper msgUnitWrapper = messageQueue.pull();
        ...


My need is to find a place to notify the PersistenceDriver that message has to be erased ...

I hope to been clear enough ??
