Method Summary | |
void |
decrementMessageCountAndMaybeDelete(MessageIdentity messageIdentity,
MessageAck ack)
Decrement the reference count of this message ID and if there are no more references then delete the message from persistent store (or maybe archive it off somewhere) |
MessageIdentity |
getLastestMessageIdentity()
Returns the last message identity that was delivered on this container which can then be used as a checkpoint so that when new durable consumers start, we know where to checkpoint their subscriptions. |
SubscriberEntry |
getSubscriberEntry(ConsumerInfo info)
Finds the subscriber entry for the given consumer info |
void |
incrementMessageCount(MessageIdentity messageId)
Increments the reference count of the message ID as its been dispatched to another subscriber. |
void |
recoverSubscription(Subscription subscription,
MessageIdentity lastDispatchedMessage)
For the new subcription find the last acknowledged message ID and then find any new messages since then and dispatch them to the subscription. |
void |
setLastAcknowledgedMessageIdentity(Subscription subscription,
MessageIdentity messageIdentity)
Stores the last acknowledged messgeID for the given subscription so that we can recover and commence dispatching messages from the last checkpoint |
void |
setMessageContainer(MessageContainer container)
Called before the service is started so that the store can communicate with the container when recovering |
void |
setSubscriberEntry(ConsumerInfo info,
SubscriberEntry subscriberEntry)
Inserts or updates the subscriber info due to a subscription change |
