As far as I know, the column type is determined by the table schema for the datbase, and the JDBC driver. > If the user codes correctly to the API, is it possible for the CCE to be > thrown? If the user properly matches the generic with what is in the table schema, a CCE should not be thrown. > Part of the idea of generics is to do away with unnecessary casts and > instanceof checks; adding inappropriate @SuppressWarnings tags negates > the benefit (and can even make things worse). Because we only have the getObject method (there are other JDBC methods; however, we cannot pick the correct method because of type erasure), there will need to be a cast. However, this cast is done by the library, so the user is not forced to cast.
