org.springframework.oxm.xmlbeans
Class XmlBeansMarshaller

java.lang.Object
  extended by org.springframework.oxm.AbstractMarshaller
      extended by org.springframework.oxm.xmlbeans.XmlBeansMarshaller
All Implemented Interfaces:
Marshaller, Unmarshaller

public class XmlBeansMarshaller
extends AbstractMarshaller

Implementation of the Marshaller interface for XMLBeans. Further options can be set by setting the xmlOptions property. The XmlOptionsFactoryBean is provided to easily wire up XmlOptions instances.

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

Note that due to the nature of XMLBeans, this marshaller requires all passed objects to be of type XmlObject.

Since:
1.0.0

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

The default implementation delegates to XmlBeansUtils. Can be overridden in subclasses.

A boolean flag is used to indicate whether this exception occurs during marshalling or unmarshalling, since XMLBeans itself does not make this distinction in its exception hierarchy.

Parameters:
ex - XMLBeans Exception that occured
marshalling - indicates whether the exception occurs during marshalling (true), or unmarshalling (false)
Returns:
the corresponding XmlMappingException
See Also:
XmlBeansUtils.convertXmlBeansException(Exception,boolean)

public void validate(XmlObject object)
              throws XmlBeansValidationFailureException
Validates the given XmlObject.

Parameters:
object - the xml object to validate
