      • toArray

        java.lang.Object[] toArray​(java.sql.ResultSet rs)
                    throws java.sql.SQLException
        Create an Object[] from the column values in one ResultSet row. The ResultSet should be positioned on a valid row before passing it to this method. Implementations of this method must not alter the row position of the ResultSet.
        Parameters:
        rs - ResultSet that supplies the array data
        Returns:
        the newly created array
        Throws:
        java.sql.SQLException - if a database access error occurs

      • toBean

        <T> T toBean​(java.sql.ResultSet rs,
             java.lang.Class<? extends T> type)
      throws java.sql.SQLException
        Create a JavaBean from the column values in one ResultSet row. The ResultSet should be positioned on a valid row before passing it to this method. Implementations of this method must not alter the row position of the ResultSet.
        Type Parameters:
        T - The type of bean to create
        Parameters:
        rs - ResultSet that supplies the bean data
        type - Class from which to create the bean instance
        Returns:
        the newly created bean
        Throws:
        java.sql.SQLException - if a database access error occurs

      • toBeanList

        <T> java.util.List<T> toBeanList​(java.sql.ResultSet rs,
                                 java.lang.Class<? extends T> type)
                          throws java.sql.SQLException
        Create a List of JavaBeans from the column values in all ResultSet rows. ResultSet.next() should not be called before passing it to this method.
        Type Parameters:
        T - The type of bean to create
        Parameters:
        rs - ResultSet that supplies the bean data
        type - Class from which to create the bean instance
        Returns:
        A List of beans with the given type in the order they were returned by the ResultSet.
        Throws:
        java.sql.SQLException - if a database access error occurs

      • toMap

        java.util.Map<java.lang.String,​java.lang.Object> toMap​(java.sql.ResultSet rs)
                                                      throws java.sql.SQLException
        Create a Map from the column values in one ResultSet row. The ResultSet should be positioned on a valid row before passing it to this method. Implementations of this method must not alter the row position of the ResultSet.
        Parameters:
        rs - ResultSet that supplies the map data
        Returns:
        the newly created Map
        Throws:
