public abstract class BaseTypeHandler<T>
extends TypeReference<T>
implements TypeHandler<T>

The base TypeHandler for references a generic type.

Important: Since 3.5.0, This class never call the ResultSet.wasNull() and CallableStatement.wasNull() method for handling the SQL NULL value. In other words, null value handling should be performed on subclass.
