Method Detail

getVisitor

public static ReflectiveVisitor getVisitor()

This method lets us keep Main as-is before and after your implementation. Suggestion: develop as follows. Step 1: replace the return below with return new SymtabVisitor(new ClassBuildSymtab()); This will use your visitor but the class symbol table implementation Step 2: [ not necessary but if you want] replace the return below with return new SymtabVisitor(new BuildSymtab()); This will use your visitor and your symbol table implementation

defaultVisit

public void defaultVisit(java.lang.Object o)

This method will cause the whole AST to be visited, but nothing will happen. It's good default behavior, but you'll need methods to handle various node types.

Overrides:
