类 XmlAdapter<ValueType,BoundType>

java.lang.Object  

javax.xml.bind.annotation.adapters.XmlAdapter<ValueType,BoundType>

类型参数：

BoundType - JAXB 不知道如何处理的一些类型。编写一个适配器，以便允许通过 ValueType 将此类型用作内存表示形式。

ValueType - JAXB 无需其他操作便知道如何处理的类型。

在编组或解组过程中，由 JAXB 绑定框架调用这些方法：

• XmlAdapter.marshal(...)：编组过程中，JAXB 绑定框架调用 XmlAdapter.marshal(..) 将 bound 类型修改为 value 类型，然后将 value 类型编组为 XML 表示形式。
• XmlAdapter.unmarshal(...)：解组过程中，JAXB 绑定框架首先将 XML 表示形式解组为 value 类型，然后调用 XmlAdapter.unmarshal(..) 将 value 类型修改为 bound 类型。
