| static bool ContainsIncompleteClassType | ( | QualType | Ty | ) | [static] |
ContainsIncompleteClassType - Returns whether the given type contains an incomplete class type. This is true if
The given type is an incomplete class type. The given type is a pointer type whose pointee type contains an incomplete class type. The given type is a member pointer type whose class is an incomplete class type. The given type is a member pointer type whoise pointee type contains an incomplete class type. is an indirect or direct pointer to an incomplete class type.
