 String attribute)

startDocument

public void startDocument()
                   throws TransformerException

Output start of document

Overrides:

startDocument in class XMLEmitter

Throws:

TransformerException

startElement

public void startElement(int nameCode,
 Attributes atts,
 int[] namespaces,
 int nscount)
                  throws TransformerException

Output element start tag

Overrides:

startElement in class XMLEmitter

Parameters:

namespaces - Array of namespace codes identifying the namespace prefix/uri pairs associated with this element

nscount - Number of significant entries within namespaces array

Throws:

TransformerException

writeAttribute

protected void writeAttribute(int elCode,
 String attname,
 String type,
 String value)
                       throws TransformerException

Write attribute name=value pair. Overrides the XML behaviour if the name and value are the same (we assume this is a boolean attribute to be minimised), or if the value is a URL.

Overrides:

writeAttribute in class XMLEmitter

Throws:

TransformerException

writeEscape

protected void writeEscape(char[] ch,
 int start,
 int length,
 boolean inAttribute)
                    throws IOException

Escape characters. Overrides the XML behaviour

Overrides:

writeEscape in class XMLEmitter

Parameters:

ch - The character array containing the string

start - The start position of the input string within the character array

length - The length of the input string within the character array This method converts the XML special characters (such as invalid input: '<' and invalid input: '&') into their predefined entities.

Throws:

IOException
