public class DOMOutputStream

extends java.io.PipedOutputStream

Write to a DOM Document.

Much like a FileOutputStream writes the stream to a File this class writes the stream directly to a DOM tree. This is however done with the use of two threads; so this class should probably not be used in EJB:s. When the writing is finished it is possible to get the Document with getDocument().
