public java.lang.Object evaluate(Node node, Evaluator pv) throws EvaluationException
CallbackEvaluationI
pv.eval(node.jjtGetChild(i))for each child. The SymbolTable is not passed as an argument. This is because it is better practice to get and set variable values by using node.getVar().setValue() rather that through the SymbolTable with requires a hashtable lookup.
node
- The current nodepv
- The visitor, can be used evaluate the children
