checkArguments
public void checkArguments(ExpressionVisitor visitor) throws XPathException
Description copied from class:SystemFunction
Method called during static type checking- Overrides:
checkArguments
in classSystemFunction
- Parameters:
visitor
- the expression visitor- Throws:
XPathException
-
preEvaluate
public Expression preEvaluate(ExpressionVisitor visitor)
preEvaluate: this method suppresses compile-time evaluation by doing nothing- Overrides:
preEvaluate
in classFunctionCall
- Parameters:
visitor
- an expression visitor- Returns:
- the result of the early evaluation, or the original expression, or potentially a simplified expression
-
evaluateItem
public Item evaluateItem(XPathContext context) throws XPathException
This method handles evaluation of the function: it returns a StringValue in the case of unparsed-text(), or a BooleanValue in the case of unparsed-text-available()- Specified by:
evaluateItem
in interfaceEvaluableItem
- Overrides:
evaluateItem
in classExpression
- 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
-
main
public static void main(java.lang.String[] args) throws java.lang.Exception
- Throws:
java.lang.Exception
