    • Method Detail

      • getArg0

        public Expression getArg0()
        Return the first argument passed to the function (at index 0).
        Returns:
        An expression that represents the first argument passed to the function.
      • setArg

        public void setArg​(Expression arg,
                           int argNum)
                    throws WrongNumberArgsException
        Set an argument expression for a function. This method is called by the XPath compiler.
        Overrides:
        setArg in class Function
        Parameters:
        arg - non-null expression that represents the argument.
        argNum - The argument number index.
        Throws:
        WrongNumberArgsException - If the argNum parameter is greater than 0.
      • canTraverseOutsideSubtree

        public boolean canTraverseOutsideSubtree()
        Tell if this expression or it's subexpressions can traverse outside the current subtree.
        Overrides:
        canTraverseOutsideSubtree in class Expression
        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.
        Specified by:
        fixupVariables in class Expression
        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).
      • deepEquals

        public boolean deepEquals​(Expression expr)
        Description copied from class: Expression
        Compare this object with another object and see if they are equal, include the sub heararchy.
        Overrides:
        deepEquals in class Function
        Parameters:
        expr - Another expression object.
        Returns:
        true if this objects class and the expr object's class are the same, and the data contained within both objects are considered equal.
