        public void setParameterId​(int id)
        Allocate a number which is essentially an alias for the parameter name, unique within a stylesheet
        Parameters:
        id - the parameter id
      • getParameterId

        public int getParameterId()
        Get the parameter id, which is essentially an alias for the parameter name, unique within a stylesheet
        Returns:
        the parameter id
      • getInstructionNameCode

        public int getInstructionNameCode()
        Description copied from class: GeneralVariable
        Get the name of this instruction (that is xsl:variable, xsl:param etc) for diagnostics
        Overrides:
        getInstructionNameCode in class GeneralVariable
        Returns:
        the name of this instruction, as a name pool name code
      • processLeavingTail

        public TailCall processLeavingTail​(XPathContext context)
                                    throws XPathException
        Description copied from class: Instruction
        ProcessLeavingTail: called to do the real work of this instruction. This method must be implemented in each subclass. The results of the instruction are written to the current Receiver, which can be obtained via the Controller.
        Specified by:
        processLeavingTail in interface TailCallReturner
        Specified by:
        processLeavingTail in class Instruction
        Parameters:
        context - The dynamic context of the transformation, giving access to the current node, the current variables, etc.
        Returns:
        null if the instruction has completed execution; or a TailCall indicating a function call or template call that is delegated to the caller, to be made after the stack has been unwound so as to save stack space.
        Throws:
        XPathException
      • getXPathExpressions

        public static void getXPathExpressions​(WithParam[] params,

                                             throws XPathException
        Evaluate the variable (method exists only to satisfy the interface)
        Parameters:
        context - the XPath dynamic evaluation context
        Returns:
