Class HL7XMLWriter

java.lang.Object
  org.regenstrief.xhl7.HL7XMLWriter

All Implemented Interfaces:

org.xml.sax.ContentHandler, HL7XMLLiterate, XMLWriter

public class HL7XMLWriter

extends java.lang.Object

implements org.xml.sax.ContentHandler, HL7XMLLiterate, XMLWriter

A SAX ContentHandler that produces traditionally encoded HL7 messages from XML/SAX events. Message is sent to the OutputStream set for the Writer.

This ContentHandler is also its own facotry.

Constructor Detail

HL7XMLWriter

public HL7XMLWriter()

Default constructor used when instantiated by reflection.

HL7XMLWriter

public HL7XMLWriter(java.io.OutputStream outputStream)

Convenient constructor that calls setOutputStream.

Parameters:

outputStream - where the serialized HL7 goes.

Method Detail

setOutputStream

public void setOutputStream(java.io.OutputStream outputStream)

Set the output stream destination.

Specified by:

setOutputStream in interface XMLWriter

Parameters:

outputStream - where the serialized HL7 goes.

getContentHandler

public org.xml.sax.ContentHandler getContentHandler()

Get the content handler. This HL7XMLWriter is itself a content handler, so it returns itself. But the XMLWriter interface is written such that the content handler could be a helper object.

If no outputStream was set previously, an output stream to standard out is used instead.

Specified by:

getContentHandler in interface XMLWriter

Returns:

itself as a content handler.

characters

public void characters(char[] ch,
                       int start,
                       int length)
                throws org.xml.sax.SAXException

For the ContentHandler interface.

Specified by:

characters in interface org.xml.sax.ContentHandler

Throws:

org.xml.sax.SAXException

startElement

                         org.xml.sax.Attributes atts)
                  throws org.xml.sax.SAXException

For the ContentHandler interface.

Specified by:

startElement in interface org.xml.sax.ContentHandler

Throws:

org.xml.sax.SAXException

endElement

public void endElement(java.lang.String namespaceURI,
                       java.lang.String localName,
                       java.lang.String qName)
                throws org.xml.sax.SAXException

For the ContentHandler interface.

Specified by:
