Interface Tasklet

All Known Implementing Classes:

TaskletAdapter

public interface Tasklet

Interface for encapsulating processing logic that is not natural to split into read-(transform)-write phases, such as invoking a system command or a stored procedure.
Since the batch framework has no visibility inside the execute() method, developers should consider implementing StepExecutionListener and check the StepExecution.isTerminateOnly() value for long lasting processes to enable prompt termination of processing on user request.
It is expected the read-(transform)-write separation will be appropriate for most cases and developers should implement ItemReader and ItemWriter interfaces then (typically extending or composing provided implementations).
