makeOptimizedFunctionCall
public Expression makeOptimizedFunctionCall(ExpressionVisitor visitor, ContextItemStaticInfo contextInfo, Expression... arguments) throws XPathException Allow the function to create an optimized call based on the values of the actual arguments- Overrides:
makeOptimizedFunctionCall
in classSystemFunction
- Parameters:
visitor
- the expression visitorcontextInfo
- information about the context itemarguments
- the supplied arguments to the function call. Note: modifying the contents of this array should not be attempted, it is likely to have no effect.- Returns:
- either a function call on this function, or an expression that delivers the same result, or null indicating that no optimization has taken place
- Throws:
XPathException
- if an error is detected
