      • evaluate

        public java.lang.String evaluate​(XPathContext xctxt,
                                         int context,

      • isContextInsensitive

        public boolean isContextInsensitive()
        Test whether the AVT is insensitive to the context in which it is being evaluated. This is intended to facilitate compilation of templates, by allowing simple AVTs to be converted back into strings. Currently the only case we recognize is simple strings. ADDED 9/5/2000 to support compilation experiment
        Returns:
        True if the m_simpleString member of this AVT is not null

        Returns:
        true if traversal outside the context node's subtree can occur.
      • fixupVariables

        public void fixupVariables​(java.util.Vector vars,
                                   int globalsSize)
        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).
      • 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.
        Specified by:
        callVisitors in interface XSLTVisitable
        Parameters:
        visitor - The visitor whose appropriate method will be called.
