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
  - getStaticBaseURI
```
public java.lang.String getStaticBaseURI()
```
    Get the static base URI of the expression
  - copy
```
public Expression copy()
```
    Copy an expression. This makes a deep copy.
    
    Overrides:
    
    copy in class SystemFunction
    
    Returns:
    
    the copy of the original expression
  - evaluateItem
```
public Item evaluateItem(XPathContext context)
                  throws XPathException
```
    Evaluate the function at run-time
    
    Specified by:
    
    evaluateItem in interface EvaluableItem
    
    Overrides:
    
    evaluateItem in class Expression
    
    Parameters:
    
    context - The context in which the expression is to be evaluated
    
    Returns:
    
    the node or atomic value that results from evaluating the expression; or null to indicate that the result is an empty sequence
    
    Throws:
    
    XPathException - if any dynamic error occurs evaluating the expression
  - tryToExpand
```
public static java.lang.String tryToExpand(java.lang.String systemId)
```
    If a system ID can't be parsed as a URL, try to expand it as a relative URI using the current directory as the base URI.
  - escapeSpaces
```
public static java.lang.String escapeSpaces(java.lang.String s)
```
    Replace spaces by %20
