AVTPartXPath(String val, PrefixResolver nsNode, XPathParser xpathProcessor, XPathFactory factory, XPathContext liaison)
Construct a simple AVT part.

Method Summary | |
---|---|
void | callVisitors(XSLTVisitor visitor) |
boolean | canTraverseOutsideSubtree()
Tell if this expression or it's subexpressions can traverse outside
the current subtree.
|
void | evaluate(XPathContext xctxt, FastStringBuffer buf, int context, PrefixResolver nsNode)
Write the value into the buffer.
|
void | fixupVariables(Vector vars, int globalsSize)
This function is used to fixup variables from QNames to stack frame
indexes at stylesheet build time. |
String | getSimpleString()
Get the AVT part as the original string.

Parameters: xpath Xpath section of AVT
Parameters: 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 parser factory XPath factory liaison 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.
Throws: javax.xml.transform.TransformerException TODO: Fix or remove this unused c'tor.
See Also: callVisitors
Returns: true if traversal outside the context node's subtree can occur.
Parameters: 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).
Throws: javax.xml.transform.TransformerException
Parameters: 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).
Returns: the AVT part as the original string.
