 <div class="block">This class provides a mechanism to obtain the EclipseLink implementation of various SDO runtime
  classes based on a given SDO class/interface. This is useful for accessing extended EclipseLink
  features. Using this helper class will alleviate the need for consumers of EclipseLink SDO to
  perform casts where their code makes use of the standard SDO API. In addition, a given SDO
  class/interface can be unwrapped based on a user-specified class. This will allow access - in
  certain cases - to a given SDO implementation class' underlying class(es). For example, an
  XMLHelper could be unwrapped resulting in an EclipseLink SDOXMLHelper or its underlying
  XMLContext.</div>
