public void checkArguments(ExpressionVisitor visitor)
                    throws XPathException
```
    Description copied from class: SystemFunction
    
    Method called during static type checking
    
    Overrides:
    
    checkArguments in class SystemFunction
    
    Parameters:
    
    visitor - the expression visitor
    
    Throws:
    
    XPathException
  - copy
```
public Expression copy()
```
    Copy an expression. This makes a deep copy.
    
    Overrides:
    
    copy in class SystemFunction
    
    Returns:
    
    the copy of the original expression
  - isUpdatingExpression
```
public boolean isUpdatingExpression()
```
    Determine whether this is an updating expression as defined in the XQuery update specification
    
    Overrides:
    
    isUpdatingExpression in class Expression
    
    Returns:
    
    true if this is an updating expression
  - evaluatePendingUpdates
```
public void evaluatePendingUpdates(XPathContext context,
                                   PendingUpdateList pul)
                            throws XPathException
```
    Evaluate an updating expression, adding the results to a Pending Update List. The default implementation of this method, which is used for non-updating expressions, throws an UnsupportedOperationException
    
    Overrides:
    
    evaluatePendingUpdates in class Expression
    
    Parameters:
    
    context - the XPath dynamic evaluation context
    
    pul - the pending update list to which the results should be written
    
    Throws:
    
    XPathException
