run
Description copied from class:Job
Executes this job. Returns the result of the execution.The provided monitor can be used to report progress and respond to cancellation. If the progress monitor has been canceled, the job should finish its execution at the earliest convenience and return a result status of severity
IStatus.CANCEL
. The singleton cancel statusStatus.CANCEL_STATUS
can be used for this purpose. The monitor is only valid for the duration of the invocation of this method.This method must not be called directly by clients. Clients should call
schedule
, which will in turn cause this method to be called.Jobs can optionally finish their execution asynchronously (in another thread) by returning a result status of
Job.ASYNC_FINISH
. Jobs that finish asynchronously must specify the execution thread by callingsetThread
, and must indicate when they are finished by calling the methoddone
. -
shouldRun
public boolean shouldRun()Description copied from class:Job
Returns whether this job should be run. Iffalse
is returned, this job will be discarded by the job manager without running.This method is called immediately prior to calling the job's run method, so it can be used for last minute precondition checking before a job is run. This method must not attempt to schedule or change the state of any other job.
Clients may override this method. This default implementation always returns
true
