ValidatingItemProcessor (Spring Batch 4.1.4.RELEASE API)

java.lang.Object
- org.springframework.batch.item.validator.ValidatingItemProcessor<T>

All Implemented Interfaces:
ItemProcessor<T,T>, org.springframework.beans.factory.InitializingBean
Direct Known Subclasses:
BeanValidatingItemProcessor
```
public class ValidatingItemProcessor<T>
extends java.lang.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.
