Class AVTPartXPath
- Serializable, XSLTVisitable
public class AVTPartXPath
Simple string part of a complex AVT.
AVTPartXPath
public AVTPartXPath(String val,
PrefixResolver nsNode,
XPathParser xpathProcessor,
XPathFactory factory,
XPathContext liaison)
throws TransformerException
Construct a simple AVT part.
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.
AVTPartXPath
public AVTPartXPath(XPath xpath)
Construct a simple AVT part.
xpath
- Xpath section of AVT
canTraverseOutsideSubtree
public boolean canTraverseOutsideSubtree()
Tell if this expression or it's subexpressions can traverse outside
the current subtree.
- canTraverseOutsideSubtree in interface AVTPart
- true if traversal outside the context node's subtree can occur.
evaluate
public void evaluate(XPathContext xctxt,
FastStringBuffer buf,
int context,
PrefixResolver nsNode)
throws TransformerException
Write the value into the buffer.
- evaluate in interface AVTPart
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).
fixupVariables
public void fixupVariables(Vector vars,
int globalsSize)
This function is used to fixup variables from QNames to stack frame
indexes at stylesheet build time.
- fixupVariables in interface 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).
getSimpleString
public String getSimpleString()
Get the AVT part as the original string.
- getSimpleString in interface AVTPart
- the AVT part as the original string.
