Method Summary | |
void |
decrementMessageCountAndMaybeDelete(MessageIdentity msgId)
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) |

deleteSubscription(String sub)
|
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(String subscriptionId,
MessageIdentity lastDispatchedMessage,
RecoveryListener listener)
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(String 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 |
setSubscriberEntry(ConsumerInfo info,
SubscriberEntry subscriberEntry)
Inserts or updates the subscriber info due to a subscription change |
void |
stop()
Called to shutdown the service |
