public AVTPartXPath(XPath xpath)
xpath
- Xpath section of AVTpublic AVTPartXPath(String val, PrefixResolver nsNode, XPathParser xpathProcessor, XPathFactory factory, XPathContext liaison) throws TransformerException
val
- A pure string section of an AVT.nsNode
- An object which can be used to determine the
Namespace Name (URI) for any Namespace prefix used in the XPath.
Usually this is based on the context where the XPath was specified,
such as a node within a Stylesheet.xpathProcessor
- XPath parserfactory
- XPath factoryliaison
- An XPathContext object, providing infomation specific
to this invocation and this thread. Maintains SAX output state,
variables, error handler and so on, so the transformation/XPath
object itself can be simultaneously invoked from multiple threads.TransformerException
- TODO: Fix or remove this unused c'tor.public void fixupVariables(Vector vars, int globalsSize)
fixupVariables
in class AVTPart
vars
- List of QNames that correspond to variables. This list
should be searched backwards for the first qualified name that
corresponds to the variable reference qname. The position of the
QName in the vector from the start of the vector will be its position
in the stack frame (but variables above the globalsTop value will need
to be offset to the current stack frame).public boolean canTraverseOutsideSubtree()

xctxt
- An XPathContext object, providing infomation specific
to this invocation and this thread. Maintains SAX state, variables,
error handler and so on, so the transformation/XPath object itself
can be simultaneously invoked from multiple threads.buf
- Buffer to write into.context
- The current source tree context.nsNode
- The current namespace context (stylesheet tree context).TransformerException

visitor
- The visitor whose appropriate method will be called.XSLTVisitable.callVisitors(XSLTVisitor)
