void doWork(Work work) throws WorkException
Work
instance for processing. This call
blocks until the Work
instance completes execution.
There is no guarantee on when the accepted Work
instance would start execution ie., there is no time constraint
to start execution.
work
- The unit of work to be done.
Could be long or short-lived.
WorkRejectedException
- indicates that a
Work
instance has been rejected from further processing.
This can occur due to internal factors.
WorkCompletedException
- indicates that a
Work
instance has completed execution with an exception.
WorkException
void doWork(Work work, long startTimeout, ExecutionContext execContext, WorkListener workListener) throws WorkException
Work
instance for processing. This call
blocks until the Work
instance completes execution.
work
- The unit of work to be done.
Could be long or short-lived.startTimeout
- a time duration (in milliseconds)
within which the execution of the Work
instance must
start. Otherwise, the Work
instance is rejected with a
WorkRejectedException
set to an appropriate error code
(WorkRejectedException.TIMED_OUT
). Note, this
does not offer real-time guarantees.execContext
- an object containing the execution
context with which the submitted Work
instance must
be executed.workListener
- an object which would be notified
when the various Work
processing events (work accepted,
work rejected, work started, work completed) occur.
WorkRejectedException
- indicates that a
Work
instance has been rejected from further processing.
This can occur due to internal factors or start timeout expiration.
WorkCompletedException
- indicates that a
Work
instance has completed execution with an exception.
WorkException
long startWork(Work work) throws WorkException
Work
instance for processing. This call
blocks until the Work
instance starts execution
but not until its completion. There is no guarantee on when
the accepted Work
instance would start
execution ie., there is no time constraint to start execution.

real-time guarantees. It is valid to return -1, if the actual start
delay duration is unknown.
