expressionBaseURI
java.lang.String expressionBaseURI
ResolveURI
public ResolveURI()
checkArguments
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
