Uses of Location in journal.io.api

Methods in journal.io.api that return Location

Modifier and Type	Method and Description
Location	Journal.write(byte[] data, Journal.WriteType write) Write the given byte buffer record, either sync (if WriteType.SYNC) or async (if WriteType.ASYNC), and returns the stored Location. A sync write causes all previously batched async writes to be synced too.
Location	Journal.write(byte[] data, Journal.WriteType write, WriteCallback callback) Write the given byte buffer record, either sync (if WriteType.SYNC) or async (if WriteType.ASYNC), and returns the stored Location. A sync write causes all previously batched async writes to be synced too. The provided callback will be invoked if sync is completed or if some error occurs during syncing.

Methods in journal.io.api that return types with arguments of type Location

Modifier and Type	Method and Description
Iterable<Location>	Journal.redo() Return an iterable to replay the journal by going through all records locations.
Iterable<Location>	Journal.redo(Location start) Return an iterable to replay the journal by going through all records locations starting from the given one.
Iterable<Location>	Journal.undo() Return an iterable to replay the journal in reverse, starting with the newest location and ending with the first.
Iterable<Location>	Journal.undo(Location end) Return an iterable to replay the journal in reverse, starting with the newest location and ending with the specified end location.

Methods in journal.io.api with parameters of type Location

Modifier and Type	Method and Description
int	Location.compareTo(Location o)
void	Journal.delete(Location location) Delete the record at the given Location. Deletes cause first a batch sync and always are logical: records will be actually deleted at log cleanup time.
void	WriteCallback.onError(Location location, Throwable error) Method called after failed write syncing.
void	WriteCallback.onSync(Location syncedLocation) Method called after successful write syncing.
byte[]	Journal.read(Location location, Journal.ReadType read) Read the record stored at the given Location, either by syncing with the disk state (if ReadType.SYNC) or by taking advantage of speculative disk reads (if ReadType.ASYNC); the latter is faster, while the former is slower but will suddenly detect deleted records.
Iterable<Location>	Journal.redo(Location start) Return an iterable to replay the journal by going through all records locations starting from the given one.
void	ReplicationTarget.replicate(Location startLocation, byte[] data)
Iterable<Location>	Journal.undo(Location end) Return an iterable to replay the journal in reverse, starting with the newest location and ending with the specified end location.

Method parameters in journal.io.api with type arguments of type Location

Modifier and Type	Method and Description
void	RecoveryErrorHandler.onError(Journal journal, List<Location> locations) Invoked by the journal during its recovery process in case of a checksum error for the given locations.
void	RecoveryErrorHandler.AbortOnError.onError(Journal journal, List<Location> locations)
void	RecoveryErrorHandler.DeleteOnError.onError(Journal journal, List<Location> locations)
void	RecoveryErrorHandler.IgnoreOnError.onError(Journal journal, List<Location> locations)
