[cfe-dev] How to know in what CXXRecordDecl is a Stmt?

[victor]

Well, as I said, not necessarily - you will definitely find a 
CXXMethodDecl, but from there you have to go to its CXXRecordDecl 
directly, not via getParents(), as it might be an out-of-line 
definition.
Ok, that's much clearer. I hope I can implement it without problems.

No, you get the children directly from the AST nodes.
Sorry if my question is too trivial, but I am not so expert using these libraries. I can find children in Stmt:
http://clang.llvm.org/doxygen/classclang_1_1Stmt.html#a489148e5d234a5a7f00d8b02981bcee5

but I couldn't find it in Decl. What is the way in this case?

Oh, thanks, I didn't know that method. 

Note that you'll not always end up in a CXXRecordDecl - sometimes you'll
 also end up in a method decl that is defined out-of-line.

Ok, so I will go through the ParentVector and, if finding a method decl, I will get the CXXRecordDecl of that method with getParent() in CXXMethodDecl, is this right?

BTW, Isn't there a getChildren in ASTContext for the contrary purpose? I was wondering the reason.

ASTContext (http://clang.llvm.org/doxygen/classclang_1_1ASTContext.html) has a getParents() method. Note that you'll not always end up in a CXXRecordDecl - sometimes you'll also end up in a method decl that is defined out-of-line.

Hello,


When I retrieve a Stmt in the AST, how can I know the CXXRecordDel to which that Stmt belongs to? I have been looking over the methods in the Stmt class, but I couldn't find an appropriate method to this end. 



Thanks in advance.
