void |
acknowledge(ConnectionContext context,
String clientId,
String subscriptionName,
MessageId messageId)
Stores the last acknowledged messgeID for the given subscription so that we can recover and commence dispatching messages from the last checkpoint |
protected void |
acknowledge(MessageId messageId,
org.apache.activeio.journal.RecordLocation location,
SubscriptionKey key)
|
void |
addMessage(ConnectionContext context,
Message message)
Not synchronized since the Journal has better throughput if you increase the number of concurrent writes that it is doing. |
void |
addSubsciption(SubscriptionInfo subscriptionInfo,
boolean retroactive)
Inserts the subscriber info due to a subscription change If this is a new subscription and the retroactive is false, then the last message sent to the topic should be set as the last message acknowledged by they new subscription. |

lookupSubscription(String clientId,
String subscriptionName)
Finds the subscriber entry for the given consumer info |
void |
recoverNextMessages(String clientId,
String subscriptionName,
int maxReturned,
MessageRecoveryListener listener)
For an active subscription - retrieve messages from the store for the subscriber after the lastMessageId messageId |
void |
recoverSubscription(String clientId,
String subscriptionName,
MessageRecoveryListener listener)
For the new subscription find the last acknowledged message ID and then find any new messages since then and dispatch them to the subscription. |
