All Implemented Interfaces:

Comparable<org.thymeleaf.processor.IProcessor>, org.thymeleaf.processor.IProcessor

public final class SpringErrorClassAttrProcessor
extends org.thymeleaf.standard.processor.attr.AbstractStandardSingleAttributeModifierAttrProcessor

Adds the given class to the field on which this attribute is applied, if that field contains errors. It's similar to a combination of th:classappend with a ${#fields.hasErrors()} expression.
