Method Summary

(package private) boolean	ancestorIsOk(ElemTemplateElement child) Verify that a literal result belongs to a result element, a variable, or a parameter.
protected void	appendAndPush(StylesheetHandler handler, ElemTemplateElement elem) Must include; super doesn't suffice!
void	endElement(StylesheetHandler handler, String uri, String localName, String rawName) End an ElemExsltFunction, and verify its validity.
void	startElement(StylesheetHandler handler, String uri, String localName, String rawName, org.xml.sax.Attributes attributes) Start an ElemExsltFunction.
void	validate(ElemTemplateElement elem, StylesheetHandler handler) Non-recursive traversal of FunctionElement tree based on TreeWalker to verify that there are no literal result elements except within a func:result element and that the func:result element does not contain any following siblings except xsl:fallback.

Method Detail

startElement

public void startElement(StylesheetHandler handler,
                         String uri,
                         String localName,
                         String rawName,
                         org.xml.sax.Attributes attributes)
                  throws org.xml.sax.SAXException

Start an ElemExsltFunction. Verify that it is top level and that it has a name attribute with a namespace.

Overrides:

startElement in class ProcessorTemplateElem

Parameters:

handler - non-null reference to current StylesheetHandler that is constructing the Templates.

uri - The Namespace URI, or an empty string.

localName - The local name (without prefix), or empty string if not namespace processing.

rawName - The qualified name (with prefix).

attributes - The specified or defaulted attributes.

Throws:

org.xml.sax.SAXException

appendAndPush

protected void appendAndPush(StylesheetHandler handler,
                             ElemTemplateElement elem)
                      throws org.xml.sax.SAXException

Must include; super doesn't suffice!

Overrides:

appendAndPush in class ProcessorTemplateElem

Parameters:

handler - non-null reference to current StylesheetHandler that is constructing the Templates.

elem - non-null reference to a the current template element.

Throws:

org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.

endElement

public void endElement(StylesheetHandler handler,
                       String uri,
                       String localName,
                       String rawName)
                throws org.xml.sax.SAXException

End an ElemExsltFunction, and verify its validity.

Overrides:

endElement in class ProcessorTemplateElem

Parameters:

handler - non-null reference to current StylesheetHandler that is constructing the Templates.

uri - The Namespace URI, or an empty string.

localName - The local name (without prefix), or empty string if not namespace processing.

rawName - The qualified name (with prefix).

Throws:

org.xml.sax.SAXException

validate

public void validate(ElemTemplateElement elem,
                     StylesheetHandler handler)
              throws org.xml.sax.SAXException

Non-recursive traversal of FunctionElement tree based on TreeWalker to verify that there are no literal result elements except within a func:result element and that the func:result element does not contain any following siblings except xsl:fallback.

Throws:

org.xml.sax.SAXException

ancestorIsOk

boolean ancestorIsOk(ElemTemplateElement child)

Verify that a literal result belongs to a result element, a variable, or a parameter.
