Re: [cdt-dev] Silly question on CDT classes!

You can use either one. But the I* public interface is safer, because it is less likely to change in the future.
That's why you are "discouraged" to use the other one.

One is an internal, implementation class. The other is a public interface.

      This may be a silly question but I bet you have the answer.

      I have been playing with the CDT source writing some static checkers.

      At some point while debugging I see the object class says for example CASTFunctionCallExpression.

      I cast my _expression_ to that but I get a warning discouraging the use of CASTFunctionCallExpression so I use instead IASTFunctionCallExpression.

      Therefore my question is what is the difference between C*_expression_ and I*_expression_. They seem brothers to me.

      Why is it discouraging?

      Thanks in advance,
