public class JournalPersistenceAdapter extends Object implements PersistenceAdapter, org.apache.activeio.journal.JournalEventListener, UsageListener, BrokerServiceAware
PersistenceAdapter
designed for use with a
Journal
and then check pointing asynchronously on a timeout with some
other long term persistent storage.Constructor and Description |

Modifier and Type | Method and Description |
---|---|
void |
allowIOResumption() |
void |
beginTransaction(ConnectionContext context)
This method starts a transaction on the persistent storage - which is
nothing to do with JMS or XA transactions - its purely a mechanism to
perform multiple writes to a persistent store in 1 transaction as a
performance optimization.
|
void |
checkpoint(boolean sync)
checkpoint any
|
void |
checkpoint(boolean sync,
boolean fullCheckpoint)
When we checkpoint we move all the journalled data to long term storage.
|
void |
commitTransaction(ConnectionContext context)
Commit a persistence transaction
|
JobSchedulerStore |
createJobSchedulerStore()
Creates and returns a new Job Scheduler store instance.
|
MessageStore |
createQueueMessageStore(ActiveMQQueue destination)
Factory method to create a new queue message store with the given
destination name
|
protected IOException |
createRecoveryFailedException(Exception e) |
TopicMessageStore |
createTopicMessageStore(ActiveMQTopic destinationName)
Factory method to create a new topic message store with the given
destination name
|
TransactionStore |
createTransactionStore()
Factory method to create a new persistent prepared transaction store for
XA recovery
|
protected IOException |
createWriteException(DataStructure packet,
Exception e) |
protected IOException |
createWriteException(String command,
Exception e) |
void |
deleteAllMessages()
Delete's all the messages in the persistent store.
|
boolean |
doCheckpoint()
This does the actual checkpoint.
|
long |
getCheckpointInterval() |
Set<ActiveMQDestination> |
getDestinations()
Returns a set of all the
ActiveMQDestination objects that the
persistence store is aware exist. |
File |
getDirectory() |
long |
getLastMessageBrokerSequenceId() |
long |
getLastProducerSequenceId(ProducerId id)
return the last stored producer sequenceId for this producer Id used to
suppress duplicate sends on failover reconnect at the transport when a
reconnect occurs

void |
overflowNotification(org.apache.activeio.journal.RecordLocation safeLocation)
The Journal give us a call back so that we can move old data out of the
journal.
