Class XmlBeansMarshaller

java.lang.Object

org.springframework.oxm.support.AbstractMarshaller

org.springframework.oxm.xmlbeans.XmlBeansMarshaller

All Implemented Interfaces:

Marshaller, Unmarshaller

public class XmlBeansMarshaller
extends AbstractMarshaller

Implementation of the Marshaller interface for Apache XMLBeans.

Options can be set by setting the xmlOptions property. The XmlOptionsFactoryBean is provided to easily set up an XmlOptions instance.

Unmarshalled objects can be validated by setting the validating property, or by calling the validate(XmlObject) method directly. Invalid objects will result in an ValidationFailureException.

NOTE: Due to the nature of XMLBeans, this marshaller requires all passed objects to be of type XmlObject.

Since:

3.0

Convert the given XMLBeans exception to an appropriate exception from the org.springframework.oxm hierarchy.

marshalling - indicates whether the exception occurs during marshalling (true), or unmarshalling (false)
