Examples of javax.batch.api.Decider

javax.batch.api.Decider
A Decider receives control as part of a decision element in a job. It is used to direct execution flow during job processing. It returns an exit status that updates the current job execution's exit status. This exit status value also directs the execution transition based on next, end, stop, fail child elements configured on the same decision element as the decider.
