public class AVTPartXPath extends AVTPart
Simple string part of a complex AVT.

    • AVTPartXPath

      public AVTPartXPath(XPath xpath)
      Construct a simple AVT part.
      Parameters:
      xpath - Xpath section of AVT
    • AVTPartXPath

      public AVTPartXPath(String val, PrefixResolver nsNode, XPathParser xpathProcessor, XPathFactory factory, XPathContext liaison) throws TransformerException
      Construct a simple AVT part.
      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:
      TransformerException - TODO: Fix or remove this unused c'tor.
  • Method Details

    • 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.
      Specified by:
      fixupVariables in class AVTPart
      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).
    • canTraverseOutsideSubtree

      public boolean canTraverseOutsideSubtree()
      Tell if this expression or it's subexpressions can traverse outside the current subtree.
      Overrides:
      canTraverseOutsideSubtree in class AVTPart
      Returns:
      true if traversal outside the context node's subtree can occur.
    • getSimpleString

      public String getSimpleString()
      Get the AVT part as the original string.
      Specified by:
      getSimpleString in class AVTPart
      Returns:
      the AVT part as the original string.
    • evaluate

      public void evaluate(XPathContext xctxt, FastStringBuffer buf, int context, PrefixResolver nsNode) throws TransformerException
      Write the value into the buffer.
      Specified by:
      evaluate in class AVTPart
      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:
      TransformerException
    • callVisitors

      public void callVisitors(XSLTVisitor visitor)
      Description copied from interface: XSLTVisitable
      This will traverse the heararchy, calling the visitor for each member. If the called visitor method returns false, the subtree should not be called.
      Parameters:
      visitor - The visitor whose appropriate method will be called.
