Method Details

getSimpleString
Get the AVT part as the original string.- Returns:
- the AVT part as the original string.
-
evaluate
public abstract void evaluate(XPathContext xctxt, FastStringBuffer buf, int context, PrefixResolver nsNode) throws TransformerException Write the evaluated value into the given string buffer.- Parameters:
xctxt
- The XPath context to use to evaluate this AVT.buf
- Buffer to write into.context
- The current source tree context.nsNode
- The current namespace context (stylesheet tree context).- Throws:
TransformerException
-
setXPathSupport
Set the XPath support.- Parameters:
support
- XPathContext to set.
-
canTraverseOutsideSubtree
public boolean canTraverseOutsideSubtree()Tell if this expression or it's subexpressions can traverse outside the current subtree.- Returns:
- true if traversal outside the context node's subtree can occur.
-
fixupVariables
This function is used to fixup variables from QNames to stack frame indexes at stylesheet build time.- 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).
