public interface SkipListener<T,S> extends StepListener
Interface for listener to skipped items. Callbacks will be called byStepimplementations at the appropriate time in the step lifecycle. Implementers of this interface should not assume that any method will be called immediately after an error has been encountered. Because there may be errors later on in processing the chunk, this listener will not be called until just before committing.- Author:
