javax.xml.bind.helpers Class DefaultValidationEventHandler

java.lang.Object
  javax.xml.bind.helpers.DefaultValidationEventHandler

All Implemented Interfaces:: ValidationEventHandler

public class DefaultValidationEventHandler
extends Object
implements ValidationEventHandler

Implements: ValidationEventHandler

唯一的 JAXB 1.0 默认验证事件处理程序。对于所有根据管理模式派生代码（该代码由 JAXB 1.0 绑定编译器生成）的 JAXBContext 而创建的对象，此类是默认处理程序。

此处理程序在第一次出现错误或出现严重错误时将导致解组和验证操作失败。

对于遵守 JAXB 2.0 和以后版本的映射 JAXB 的类，此处理程序不再是默认处理器。默认验证事件处理已经更改，它在 javax.xml.bind.Unmarshaller 和 javax.xml.bind.Marshaller 中指定。

JAXB1.0

英文文档：

JAXB 1.0 only default validation event handler. This is the default handler for all objects created from a JAXBContext that is managing schema-derived code generated by a JAXB 1.0 binding compiler.

This handler causes the unmarshal and validate operations to fail on the first error or fatal error.

This handler is not the default handler for JAXB mapped classes following JAXB 2.0 or later versions. Default validation event handling has changed and is specified in Unmarshaller and Marshaller.

JAXB1.0

英文文档：
handleEvent

public boolean handleEvent(ValidationEvent event)

Description copied from interface: ValidationEventHandler

Receive notification of a validation warning or error. The ValidationEvent will have a ValidationEventLocator embedded in it that indicates where the error or warning occurred.

If an unchecked runtime exception is thrown from this method, the JAXB provider will treat it as if the method returned false and interrupt the current unmarshal, validate, or marshal operation.

Specified by:: handleEvent in interface ValidationEventHandler

Parameters:: event - the encapsulated validation event information. It is a provider error if this parameter is null.
Returns:: true if the JAXB Provider should attempt to continue the current unmarshal, validate, or marshal operation after handling this warning/error, false if the provider should terminate the current operation with the appropriate UnmarshalException, ValidationException, or MarshalException.
