evaluate
Description copied from interface:CallbackEvaluationI
Performs some special evaluation on the node. This method has the responsibility for evaluating the children of the node, and it should generally callpv.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.- Parameters:
node
- The current nodepv
- The visitor, can be used evaluate the children- Returns:
- the value after evaluation. This value will be passed to other functions higher up the node tree. The value can be any type including Double or Vector<Object>
- Throws:
EvaluationException
- if the calculation cannot be performed- See Also:
