Method Detail

enqueue

public long enqueue(JournalEntry entry)

Description copied from interface: JournalDao

Adds the given entry to a journal.

Specified by:

enqueue in interface JournalDao

Parameters:

entry - entry to persist

Returns:

id generated for the entry

queueWithCustomCreationDate

@Internal
public void queueWithCustomCreationDate(JournalEntry entry,
                                                 Date creationDate)

findEntries

public List<JournalEntry> findEntries(JournalIdentifier journalId,
                                      long afterId,
                                      long ignoreWithinMillis,
                                      int maxEntries)

Description copied from interface: JournalDao

Finds journal entries that were added after an entry with the given id but earlier than given milliseconds ago. Entries are returned in ascending order of their identifier.

This method can miss some entries due to identifier assignment and entry insertion not being an atomic operation. The risk of missed entries can be reduced in two ways:

1. Create new entries as close to transaction commit as possible.
2. Increase ignoreSinceMillis value.

Specified by:

findEntries in interface JournalDao

Parameters:

journalId - only entries with this journal id will be returned

afterId - only entries with id higher than this will be returned

ignoreWithinMillis - only entries created this many milliseconds ago or earlier will be returned

maxEntries - maximum number of entries to process

Returns:

journal entries that were added after an entry with the given id

findMostRecentEntryByMessage

public com.atlassian.fugue.Option<JournalEntry> findMostRecentEntryByMessage(@Nonnull
                                                                             JournalIdentifier journalId,
                                                                             String message)

Description copied from interface: JournalDao

Finds the most recent journal entry (if any) for the given journal that exactly matches the given journal entry message. Note that this operation is likely to EXTREMELY SLOW when the journal gets above a certain size. Do not use in production code.

Specified by:

findMostRecentEntryByMessage in interface JournalDao

Parameters:

journalId - only entries with this journal id will be returned

message - the exact text of the journal entry message

Returns:

the Optional journal entry matching the search

removeEntriesOlderThan

public int removeEntriesOlderThan(Date date)

Description copied from interface: JournalDao

Removes entries from all journals that were created before the given date.

Specified by:

removeEntriesOlderThan in interface JournalDao

Parameters:

date - only entried with a date later than this will be returned

Returns:

number of removed entries

findLatestEntry

public com.atlassian.fugue.Option<JournalEntry> findLatestEntry(@Nonnull
                                                                JournalIdentifier journalId,
                                                                long ignoreWithinMillis)

Description copied from interface: JournalDao

Finds the latest journal entry if any.

Specified by:

findLatestEntry in interface JournalDao

Parameters:

journalId - identifier of the journal

ignoreWithinMillis - only entry created this many milliseconds ago or earlier will be returned

Returns:

the latest journal entry

countEntries

public int countEntries(@Nonnull
                        JournalIdentifier journalId,
                        long afterId,
                        long ignoreWithinMillis)

Description copied from interface: JournalDao

Counts the number of entries in a journal.

Specified by:

countEntries in interface JournalDao

Parameters:
