<div>Hi Clang list,<br>
<br>
I am implementing a RecursiveASTVisitor so I can rely on a preorder traversal.<br>
In some of the Visit* callbacks I would like to pass some information downwards<br>
and do something like this:<br>
<br>
bool VisitFunctionDecl(const FunctionDecl *d) {<br>
...<br>
d->getBody()->attachToContext(myAdditionalData);<br>
...<br>
}<br>
<br>
So that I can access it when the callback for the body is called:<br>
<br>
bool VisitCompoundStmt(const CompoundStmt *n) {<br>
...<br>
MyAdditionalData *myData = n->getFromContext();<br>
...<br>
}<br>
<br>
Right now I am using a std::map with the pointer as key, i.e.<br>
<br>
bool VisitFunctionDecl(const FunctionDecl *d) {<br>
...<br>
myMap[d->getBody()] = myAdditionalData;<br>
...<br>
}<br>
<br>
and then<br>
<br>
bool VisitCompoundStmt(const CompoundStmt *n) {<br>
...<br>
MyAdditionalData *myData = myMap[n];<br>
...<br>
}<br>
<br>
That works, but it does not seem to be the right thing.<br>
Is there a way to attach additional information to AST nodes?<br>
Or should I approach that in a completely different way?<br>
<br>
Thank you and best regards,<br>
Benedikt</div>
