Class PrettyPrintingXmlWriter

java.lang.Object

com.sun.xml.rpc.util.xml.PrettyPrintingXmlWriter

public class PrettyPrintingXmlWriter
extends Object

A writer of XML output streams.

An XML writer knows hardly anything about XML document well-formedness, to say nothing of validity. It relies upon the invoker to ensure that the generated document is well-formed and, if required, valid.

Note: This class is incomplete. In the next draft it will be extended to more closely mimic the Xerces XMLScanner, and to support output to both SAX streams and DOM documents.
