Class ValidatingItemProcessor<T>

java.lang.Object

org.springframework.batch.item.validator.ValidatingItemProcessor<T>

All Implemented Interfaces:

ItemProcessor<T,T>, org.springframework.beans.factory.InitializingBean

public class ValidatingItemProcessor<T>
extends Object
implements ItemProcessor<T,T>, org.springframework.beans.factory.InitializingBean

Simple implementation of ItemProcessor that validates input and returns it without modifications. Should the given Validator throw a ValidationException this processor will re-throw it to indicate the item should be skipped, unless setFilter(boolean) is set to true, in which case null will be returned to indicate the item should be filtered.
