[cfe-dev] overriding visitor methods from class RecursiveASTVisitor for clang front end

Is there any concept of level or hierarchy of classes that are 
inherited separately from RecursiveASTVisitor? because statements in 
CFGElement have hierarchy.

Say, we inherit class A and class B from RecursiveASTVisitor

class RecursiveASTVisitor has visitor functions VisitSa1Stmt(), 
VisitSa2Stmt() and VisitSb1Stmt(), VisitSb2Stmt().

class A has overridden VisitSa1Stmt(), VisitSa2Stmt() and it is 
creating CFG, calling TraverseStmt() method on instance of class B

class B has overridden VisitSb1Stmt(), VisitSb1Stmt()

Sa*Stmt may contain Sb*Stmt, e.g. then clause of IfStmt can contain 
assignment statements that has another binary operation in rhs 

then how will overridden methods be invoked?
