The class object for a class * implementing the <code>SQLData interface will be entered in the * appropriate <code>Connection object's type map along with the SQL * name of the UDT for which it is a custom mapping. * <P> * Typically, a <code>SQLData implementation * will define a field for each attribute of an SQL structured type or a * single field for an SQL <code>DISTINCT type. When the UDT is * retrieved from a data source with the <code>ResultSet.getObject * method, it will be mapped as an instance of this class. A programmer * can operate on this class instance just as on any other object in the * Java programming language and then store any changes made to it by * calling the <code>PreparedStatement.setObject method, * which will map it back to the SQL type. * <p> * It is expected that the implementation of the class for a custom * mapping will be done by a tool. In a typical implementation, the * programmer would simply supply the name of the SQL UDT, the name of * the class to which it is being mapped, and the names of the fields to * which each of the attributes of the UDT is to be mapped. The tool will use * this information to implement the <code>SQLData.readSQL and * <code>SQLData.writeSQL methods.
