Creating a new SAML Object Unmarshaller

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

Additional Configuration

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.
