[cfe-dev] Better way obtaining dereference?

[Zong]

Dear All,


I would like to know is that a better way in Clang to obtain the number of UnaryOperator in UnaryOperatorClass Stmt (i.e., for ***a, return 3)?


Currently, I write a recursive function to strip the the UnaryOperator, until it reaches DeclRefExpr . Thanks.


Best, 
Zong
