Woops, sorry, for some reason I missed that there already have been
plenty of answers.

The way I'd go would be to first locate the CXXConstructorDecl that is
being called, look through its parameter list, get the index of the
parameter named "x", and then find the expression on that index in the
argument list.

So as far as I know there is no more direct way of doing this.

I have a class with a large number of constructors which differ only

slightly. I'd like to be able to distinguish these by looking at the

names of the arguments, but I cannot seem to find them.

class A {


      A(int x);

      A(int x, float y);

      A(double w, int x, char *z);



I'd like to be able to (for example) look at a particular

CXXConstructExpr and get the value of "x", whichever position "x" may


Where should I be looking?
