ABSTRACT:
Methods and apparatus for enabling an object associated with an XML node class to be used for both a document object model (DOM) application programming interface (API) that supports an in-memory representation of XML nodes and a DOM API that supports a database-backed representation of XML nodes are disclosed. According to one aspect of the present invention, a method for creating an object that represents an XML node in a Java space includes determining whether the object is to represent a pure node. An object of a first class is created to represent a database-backed node when the object is not determined to represent the pure node, and the object of the first class is created to represent a pure node when the object is determined to represent the pure node. The object includes the same set of fields whether the object represents a pure node or a database-backed node.
