[cfe-dev] How can I get the types' information in CStyleCastExpr

[Jordan Rose]

The simplest way to do this is Expr::getType. The type of the CastExpr is the casted type, the type of the CastExpr's subexpression is the original type.

If you want to get more information here, look into ExplicitCastExpr::getTypeInfoAsWritten.

Hope that helps,
Jordan
