Method Detail

addNewDocumentEvents

public void addNewDocumentEvents(Collection<? extends DocumentEvent> documentEvents)
                          throws com.redhat.lightblue.client.LightblueException

Specified by:

addNewDocumentEvents in interface DocumentEventRepository

Throws:

com.redhat.lightblue.client.LightblueException

retrievePriorityDocumentEventsUpTo

public List<LightblueDocumentEvent> retrievePriorityDocumentEventsUpTo(int maxEvents)
                                                                throws Exception

Specified by:

retrievePriorityDocumentEventsUpTo in interface DocumentEventRepository

Throws:

Exception

ensureTransactionActive

public void ensureTransactionActive(DocumentEvent event)
                             throws Exception

N.B. This implementation currently works by simply checking if the known in memory timeouts of provided event falls within some threshold. It could be updated to also timestamp the persisted event again, but to be safe we would probably want to also lock them to do this update. For now, that complexity is probably not worth it.

Specified by:

ensureTransactionActive in interface DocumentEventRepository

Throws:

Exception

public void markDocumentEventsPublishedOrFailed(Collection<? extends DocumentEvent> documentEvents,
                                                Collection<FailedDocumentEvent> failures)
                                         throws com.redhat.lightblue.client.LightblueException
