preEvaluate
public Expression preEvaluate(ExpressionVisitor visitor) throws XPathException
Compile time evaluation- Overrides:
preEvaluate
in classCompileTimeFunction
- Parameters:
visitor
- an expression visitor- Returns:
- the result of the early evaluation, or the original expression, or potentially a simplified expression
- Throws:
XPathException
