Class BeanMapper<T>

java.lang.Object

org.noorm.jdbc.BeanMapper<T>

public class BeanMapper<T>
extends Object

Generic mapper for mapping a JDBC ResultSet to a Bean or for mapping a Bean to a parameter map. This class is primarily used by the JDBCStatementProcessor to convert the JDBC ResultSets into Beans, resp. Lists of Beans. Internally, the BeanMapper uses reflection to find the correct mapping with help of the JDBCColumn annotations for the distinct attributes of the Beans. Attributes without JDBCColumn annotation are considered transient and they are omitted from the mapping procedure.
