public interface SkipListener
extends StepListener

Interface for listener to skipped items. Callbacks will be called by Step implementations at the appropriate time in the step lifecycle. Callbacks must always be made (where relevant) in a transaction that is still valid: i.e. possibly on a read error, but not on a write error.
