Base class of all events produced by
ThreadedStorageService.
Every event has an event code that indicates the state of a process when the event was
generated. The event code will also give a guide as to what information the event will contain.
The event codes, and their meanings, are:
- EVENT_STARTED: An operation has commenced, but no work has yet been done.
- EVENT_IN_PROGRESS: An operation is in progress. Progress events are fired at regular time
intervals, and will include information about any work that have been completed
as part of the overall operation.
- EVENT_COMPLETED: An operation has completed, and all the work has been done.
- EVENT_CANCELLED: An operation was started but has been cancelled before it could complete.
If an operation is cancelled, this event will be fired instead of the EVENT_COMPLETED.
- EVENT_ERROR: An operation has failed and an exception has been thrown. The error
will be availble from
#getErrorCause()
- EVENT_IGNORED_ERRORS: One or more operations have failed but ,because the
"threaded-service.ignore-exceptions-in-multi" JetS3t property value is set to true,
the overall operation has continued. The errors will be available from
#getIgnoredErrors()
EVENT_STARTED and EVENT_IN_PROGRESS events may include a
ThreadWatcher object containing
detailed information about the progress of an operation, such as how many threads have
completed and, of uploads and downloads, how many bytes have been transferred at what speed and
how long until the transfer is complete.
See the event object specific to the operation you are performing for more details about the
information available in service events.
