How to find all ifs, switch cases, etc. [message #1754567]

So traversing the hole AST with an Visitor to find all IASTIfStatements or other statements in large files is very time consuming. Is there an other way to do so? Is there a way to do that index-based?

There's no way that I know of that is index-based, the index primarily stores names and type information, not control flow (well, except for callers of functions which it does store). But if by time consuming you mean that it takes long for you to type Wink

maybe you could be interested in the Control Flow Graph code available in org.eclipse.cdt.codan.core.cxx.internal.model.cfg. It parses the AST for you and offers a higher level interface. But it will still be as slow, CPU-wise as it does traverse the AST as well.
