evaluateItem
Evaluate the expression.- Specified by:
evaluateItem
in interfaceExpression
- Overrides:
evaluateItem
in classArithmeticExpression
- 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
-
doArithmetic
public static Item doArithmetic(Expression operand0, int operator, Expression operand1, XPathContext context, boolean backwardsCompatible) throws XPathException - Throws:
XPathException
