[cfe-dev] Iterating over the constructors of a class

[Jordan Rose]

Did you miss this e-mail from me last week?

> I don't know for sure, but my guess is that the constructors declared within the CXXRecordDecl are just declarations, and the out-of-line definitions aren't showing up. You'll need to use hasBody() (on FunctionDecl) to get the particular CXXConstructorDecl that has the initializers.

Hope that helps,
Jordan

For that purpose I tried two aproaches: 1) Using the method VisitCXXConstructorDecl and 2) VisitCXXRecordDecl and then use the CXXRecordDecl::ctor_iterator. However, only when I use the approach 1) I can see that the constructor actually has initializers.
