Abstract
The concept of “renderers” and “translators” is introduced in connection with bidirectional conversion between object models and XML. A renderer embodies the logic responsible for mediating the parser specific APIs for reading and writing XML. It utilizes a plurality of translator objects, which embody the mapping information needed to convert the XML into object model instances. The translator objects themselves do not contain “knowledge” of parser implementations; thus, the translators are common and can be shared and reused by any and all renderer implementations. Since each translator embodies the knowledge and rules regarding how to convert an XML model to an object model, and how to convert object models to XML, it is thus independent of the particular renderer that is being used, whether it be SAX, DOM, or some other renderer.
