• Function3Args

  public Function3Args()

Method Detail

• getArg2

  public Expression getArg2()

  Return the third argument passed to the function (at index 2).

  Returns:

  An expression that represents the third argument passed to the function.

• 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.

  Overrides:

  fixupVariables in class Function2Args

  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).

• 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 Function2Args

  Parameters:

  arg - non-null expression that represents the argument.

  argNum - The argument number index.

  Throws:

  WrongNumberArgsException - If the argNum parameter is greater than 2.

• checkNumberArgs

  public void checkNumberArgs​(int argNum)
                       throws WrongNumberArgsException

  Check that the number of arguments passed to this function is correct.

  Overrides:

  checkNumberArgs in class Function2Args

  Parameters:

  argNum - The number of arguments that is being passed to the function.

  Throws:

  WrongNumberArgsException

• canTraverseOutsideSubtree

  public boolean canTraverseOutsideSubtree()

  Tell if this expression or it's subexpressions can traverse outside the current subtree.

  Overrides:

  canTraverseOutsideSubtree in class Function2Args

  Returns:

  true if traversal outside the context node's subtree can occur.

• callArgVisitors

  public void callArgVisitors​(XPathVisitor visitor)

  Description copied from class: Function
  Call the visitors for the function arguments.

  Overrides:

  callArgVisitors in class Function2Args

  See Also:

  XPathVisitable.callVisitors(ExpressionOwner, XPathVisitor)

• 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 Function2Args

  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.
