                                              com.atlassian.core.task.longrunning.LongRunningTask task)

Description copied from interface: LongRunningTaskManager

Start some task in a new thread

Specified by:

startLongRunningTask in interface LongRunningTaskManager

Parameters:

public com.atlassian.core.task.longrunning.LongRunningTask getLongRunningTask(com.atlassian.user.User user,
                                                                              LongRunningTaskId id)

gets a long running task with the given Id that was registered either by this user or the anonymous user.

Specified by:

getLongRunningTask in interface LongRunningTaskManager

Parameters:

user - the user responsible for the task

id - the ID of the task

Returns:

stopTrackingLongRunningTask

public void stopTrackingLongRunningTask(LongRunningTaskId id)

Description copied from interface: LongRunningTaskManager

Clean up an old task. The manager hangs on to tasks that have been completed so their status can be queried. Calling this method will remove the task from the manager entirely.

This method does not stop a task from being executed. If the task is already running it will continue to completion, you just won't be able to query its status any more.

Specified by:

stopTrackingLongRunningTask in interface LongRunningTaskManager

Parameters:

id - the ID of the task to remove.

destroy

public void destroy()
             throws Exception

Specified by:

destroy in interface org.springframework.beans.factory.DisposableBean

Throws:

Exception

stop

public void stop(long timeout,
                 TimeUnit unit)
          throws TimeoutException

Description copied from interface: LongRunningTaskManager

Stop accepting new long running tasks. All tasks that have previously been submitted will be run to completion. If this takes longer than the timeout, the method will throw an exception and the task manager will resume normal operation accepting new tasks.

Specified by:

stop in interface LongRunningTaskManager

Parameters:

timeout - the time to wait for running tasks to complete

unit - the unit of measurement for the timeout parameter

Throws:

TimeoutException - if the timeout is exceeded

resume

public void resume()

Description copied from interface: LongRunningTaskManager

Resume accepting long-running tasks after LongRunningTaskManager.stop(long, java.util.concurrent.TimeUnit) has been called. If the long-running task manager is not stopped, this method will whistle quietly to itself and do nothing.

Specified by:

resume in interface LongRunningTaskManager

taskFinished

protected void taskFinished(LongRunningTaskId id)
