protected org.xml.sax.helpers.AttributesImpl |
addNamespaceAttribute(org.xml.sax.helpers.AttributesImpl attrs,
Namespace namespace)
If isDelcareNamespaceAttributes() is enabled then this method will add
the given namespace declaration to the supplied attributes object,
creating one if it does not exist.
|
protected void |
checkForNullHandlers()
Ensures non-null content handlers?
|
protected Attributes |
createAttributes(Element element,
Attributes namespaceAttributes) |
protected void |
documentLocator(Document document)
The
Locator is only really useful when parsing a
textual document as its main purpose is to identify the line and column
number. |
protected void |
dtdHandler(Document document)
We do not yet support DTD or XML Schemas so this method does nothing
right now.
|
protected void |
endDocument() |
protected void |
endElement(Element element) |
protected void |
endPrefixMapping(NamespaceStack stack,
int stackSize)
Fires a SAX endPrefixMapping event for all the namespaceStack which have
gone out of scope

This implementation does actually use any features but just stores them
for later retrieval

Sets the given SAX property
