Create a class that extends org.opensaml.common.io.impl.AbstractSAMLObjectUnmarshaller and meets the following guidelines:

• Create a public, no argument, constructor that invokes super().

• Override processChildElement(SAMLObject, SAMLObject) if your SAMLObject contains child SAMLObjects. Be sure to call super.processChildElement(SAMLObject, SAMLObject) if your unmarshaller does not handle a given child object.

• Override processAttribute(SAMLObject, Attr) if you need to unmarshall information from XML attributes into your SAMLObject. Be sure to call super.processAttribute(SAMLObject, Attr) if your unmarshaller does not handle a given attribute.

• Override processElementContent(SAMLObject, String) if you need to unmarshall information from the XML element's content into your SAMLObject

• Ensure your unmarshaller is stateless

If your class requires additional configuration information this can be provided in the OpenSAML configuration file; refer to the Extending the ObjectProvider section for more information.
