package org.springframework.batch.item.validator;
Simple implementation of org.springframework.batch.item.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.

Author(s):
Robert Kasanicky
public class ValidatingItemProcessor<T> implements ItemProcessor<T, T>, InitializingBean {
	private Validator<? super T> validator;
	private boolean filter = false;

Default constructor
	}

Creates a ValidatingItemProcessor based on the given Validator.
	public ValidatingItemProcessor(Validator<? super T> validator) {
		this. = validator;
	}

Set the validator used to validate each item.

Parameters:
validator
	public void setValidator(Validator<? super T> validator) {
		this. = validator;
	}

Should the processor filter invalid records instead of skipping them?

Parameters:
filter
	public void setFilter(boolean filter) {
		this. = filter;
	}

Validate the item and return it unmodified

Returns:
the input item
Throws:
ValidationException if validation fails
	public T process(T itemthrows ValidationException {
		try {
		}
		catch (ValidationException e) {
			if () {
				return null// filter the item
			}
			else {
				throw e// skip the item
			}
		}
		return item;
	}
	public void afterPropertiesSet() throws Exception {
		Assert.notNull("Validator must not be null.");
	}
