[cfe-dev] A newbie question on getting operator in Expr

[Adrien Chauve]

Hi,

To simplify the code and avoid handwritten recursion, maybe you could
use the RecursiveASTVisitor insted of 3 visitors:

class MyConsumer : public ASTConsumer, public RecursiveASTVisitor<MyConsumer>
{
    virtual void HandleTranslationUnit(ASTContext &context)
    {
          // traverse AST to visit declarations and statements
          TraverseDecl(context.getTranslationUnitDecl());
    }

    bool VisitBinaryOperator(BinaryOperator* expr)
    {
         // ... handle expr
         return true;
    }

    bool VisitDeclRefExpr(DeclRefExpr* expr)
    {
          // ... handle expr
          return true;
    }
};
